summary: Learn how to work with File and Image records
# File Management
## Files, Images and Folders as database records
All files, images and folders in the 'assets' directory are stored in the database. Each record has the following database fields:
| Field name | Description |
| ---------- | ----------- |
| `ClassName` | The class name of the file (e.g. File, Image or Folder). |
| `Name` | The 'basename' of the file, or the folder name. For example 'my-image.jpg', or 'images' for a folder. |
| `Title` | The optional, human-readable title of the file for display only (doesn't apply to folders). |
| `Filename` | The path to the file/folder, relative to the webroot. For example 'assets/images/my-image.jpg', or 'assets/images/' for a folder. |
| `Content` | Typically unused, but handy for a textual representation of files. For example for fulltext indexing of PDF documents. |
| `ShowInSearch` | Whether the file should be shown in search results, defaults to '1'. See ["Tutorial 4 - Site Search"](/tutorials/site_search) for enabling search. |
| `ParentID` | The ID of the parent Folder that this File/Folder is in. A ParentID of '0' indicates that the File/Folder is in the 'assets' directory. |
| `OwnerID` | The ID of the Member that 'owns' the File/Folder (not related to filesystem permissions). |
## Management through the "Files" section of the CMS
If you have the CMS module installed, you can manage files, folders and images in the "Files" section of the CMS. Inside this section, you will see a list of files and folders like below:
![](../../_images/assets.png)
You can click on any file to edit it, or click on any folder to open it. To delete a file or a folder, simply click the red 'X' symbol next to it. If you click to open a folder, you can go back up one level by clicking the 'up' arrow above the folder name (highlighted below):
![](../../_images/assets_up.png)
Once you click to edit a file, you will see a form similar to the one below, in which you can edit the file's title, filename, owner, or even change which folder the file is located in:
![](../../_images/assets_editform.png)
You may also notice the 'Sync files' button (highlighted below). This button allows CMS users to 'synchronise' the database (remember, all files/folders are stored as database records) with the filesystem. This is particularly useful if someone has uploaded or removed files/folders via FTP, for example.
![](../../_images/assets_sync.png)
## Upload
Files can be managed through a `FileField` or an `UploadField`. The `[api:FileField]` class provides a simple HTML input with a type of "file", whereas an `[api:UploadField]` provides a much more feature-rich field (including AJAX-based uploads, previews, relationship management and file data management). See [`Reference - UploadField`](/developer_guides/forms/field_types/uploadfield) for more information about how to use the `UploadField` class.

# Image
## Introduction
Represents an image object through the `[api:Image]` class, inheriting all base functionality from the `[api:File]` class with extra functionality including resizing.
## Usage
### Managing images through form fields
Images can be uploaded like any other file, through `[api:FileField]`.
More advanced usage is possible through `[api:UploadField]`,
which provides thumbnails, a detail view of the image properties,
and management of relationships to other DataObject instances.
Allows upload of images through limiting file extensions with `setAllowedExtensions()`.
### Inserting images into the WYSIWYG editor
See [Topics: Rich Text Editing](/topics/rich-text-editing).
### Resizing Images in PHP
The following are methods defined on the GD class which you can call on Image Objects. Note to get the following to work
you need to have GD2 support in your PHP installation and because these generate files you must have write access to
your tmp folder.
:::php
// manipulation functions
$image->resize(width,height); // Basic resize, just skews the image
$image->resizeRatio(width,height) // Resizes an image with max width and height
$image->paddedResize(width,height) // Adds padding after resizing to width or height.
$image->croppedImage(width,height) // Crops the image from the centre, to given values.
$image->resizeByHeight(height) // Maximum height the image resizes to, keeps proportion
$image->resizeByWidth(width) // Maximum width the image resizes to, keeps proportion
$image->greyscale(r,g,b) // alters image channels ===
// values
$image->getHeight() // Returns the height of the image.
$image->getWidth() // Returns the width of the image
$image->getOrienation() // Returns a class constant: ORIENTATION_SQUARE or ORIENTATION_PORTRAIT or ORIENTATION_LANDSCAPE
You can also create your own functions by extending the image class, for example
:::php
class MyImage extends Image {
public function generateRotateClockwise(GD $gd) {
return $gd->rotate(90);
}
public function generateRotateCounterClockwise(GD $gd) {
return $gd->rotate(270);
}
public function clearResampledImages() {
$files = glob(Director::baseFolder().'/'.$this->Parent()->Filename."_resampled/*-$this->Name");
foreach($files as $file) {unlink($file);}
}
public function Landscape() {
return $this->getWidth() > $this->getHeight();
}
public function Portrait() {
return $this->getWidth() < $this->getHeight();
}
public function generatePaddedImageByWidth(GD $gd,$width=600,$color="fff"){
return $gd->paddedResize($width, round($gd->getHeight()/($gd->getWidth()/$width),0),$color);
}
public function Exif(){
//http://www.v-nessa.net/2010/08/02/using-php-to-extract-image-exif-data
$image = $this->AbsoluteURL;
$d=new ArrayList();
$exif = exif_read_data($image, 0, true);
foreach ($exif as $key => $section) {
$a=new ArrayList();
foreach ($section as $name => $val)
$a->push(new ArrayData(array("Title"=>$name,"Content"=>$val)));
$d->push(new ArrayData(array("Title"=>strtolower($key),"Content"=>$a)));
}
return $d;
}
}
### Resizing in Templates
You can call certain resize functions directly from the template, to use the inbuilt GD functions as the template parser
supports these, for example SetWidth() or SetHeight().
For output of an image tag with the image automatically resized to 80px width, you can use:
:::php
$Image.SetWidth(80) // returns a image 80px wide, ratio kept the same
$Image.SetHeight(80) // returns a image 80px tall, ratio kept the same
$Image.SetSize(80,80) // returns a 80x80px padded image
$Image.SetRatioSize(80,80) // Returns an image scaled proportional, with its greatest diameter scaled to 80px
$Image.CroppedImage(80,80) // Returns an 80x80 image cropped from the center.
$Image.PaddedImage(80, 80, FFFFFF) // Returns an 80x80 image. Unused space is padded white. No crop. No stretching
$Image.Width // returns width of image
$Image.Height // returns height of image
$Image.Orientation // returns Orientation
$Image.Filename // returns filename
$Image.URL // returns filename
### Form Upload
For usage on a website form, see `[api:FileField]`.
If you want to upload images within the CMS, see `[api:UploadField]`.
### Image Quality
To adjust the quality of the generated images when they are resized add the following to your mysite/config/config.yml file:
:::yml
GDBackend:
default_quality: 90
The default value is 75.
### Clearing Thumbnail Cache
Images are (like all other Files) synchronized with the SilverStripe database.
This syncing happens whenever you load the "Files & Images" interface,
and whenever you upload or modify an Image through SilverStripe.
If you encounter problems with images not appearing, or have mysteriously disappeared, you can try manually flushing the
image cache.

### Inserting images into the WYSIWYG editor
See [Topics: Rich Text Editing](/topics/rich-text-editing).
### Manipulating images in Templates
You can manipulate images directly from templates to create images that are
resized and cropped to suit your needs. This doesn't affect the original
image or clutter the CMS with any additional files, and any images you create
in this way are cached for later use. In most cases the pixel aspect ratios of
images are preserved (meaning images are not stretched).
![](../../_images/image-methods.jpg)
Here are some examples, assuming the `$Image` object has dimensions of 200x100px:
:::ss
// Scaling functions
$Image.ScaleWidth(150) // Returns a 150x75px image
$Image.ScaleMaxWidth(100) // Returns a 100x50px image (like ScaleWidth but prevents up-sampling)
$Image.ScaleHeight(150) // Returns a 300x150px image (up-sampled. Try to avoid doing this)
$Image.ScaleMaxHeight(150) // Returns a 200x100px image (like ScaleHeight but prevents up-sampling)
$Image.Fit(300,300) // Returns an image that fits within a 300x300px boundary, resulting in a 300x150px image (up-sampled)
$Image.FitMax(300,300) // Returns a 200x100px image (like Fit but prevents up-sampling)
// Cropping functions
$Image.Fill(150,150) // Returns a 150x150px image resized and cropped to fill specified dimensions (up-sampled)
$Image.FillMax(150,150) // Returns a 100x100px image (like Fill but prevents up-sampling)
$Image.CropWidth(150) // Returns a 150x100px image (trims excess pixels off the x axis from the center)
$Image.CropHeight(50) // Returns a 200x50px image (trims excess pixels off the y axis from the center)
// Padding functions (add space around an image)
$Image.Pad(100,100) // Returns a 100x100px padded image, with white bars added at the top and bottom
$Image.Pad(100, 100, CCCCCC) // Same as above but with a grey background
// Metadata
$Image.Width // Returns width of image
$Image.Height // Returns height of image
$Image.Orientation // Returns Orientation
$Image.Title // Returns the friendly file name
$Image.Name // Returns the actual file name
$Image.FileName // Returns the actual file name including directory path from web root
$Image.Link // Returns relative URL path to image
$Image.AbsoluteLink // Returns absolute URL path to image
Image methods are chainable. Example:
:::ss
<body style="background-image:url($Image.ScaleWidth(800).CropHeight(800).Link)">
### Manipulating images in PHP
The image manipulation functions can be used in your code with the same names, example: `$image->Fill(150,150)`.
Some of the MetaData functions need to be prefixed with 'get', example `getHeight()`, `getOrientation()` etc.
Please refer to the `[api:Image]` API documentation for specific functions.
### Creating custom image functions
You can also create your own functions by extending the image class, for example
:::php
class MyImage extends DataExtension {
public function Landscape() {
return $this->owner->getWidth() > $this->owner->getHeight();
}
public function Portrait() {
return $this->owner->getWidth() < $this->owner->getHeight();
}
public function PerfectSquare() {
return $this->owner->getFormattedImage('PerfectSquare');
}
public function generatePerfectSquare(Image_Backend $backend) {
return $backend->croppedResize(100,100);
}
public function Exif(){
//http://www.v-nessa.net/2010/08/02/using-php-to-extract-image-exif-data
$image = $this->owner->AbsoluteLink();
$d=new ArrayList();
$exif = exif_read_data($image, 0, true);
foreach ($exif as $key => $section) {
$a=new ArrayList();
foreach ($section as $name => $val)
$a->push(new ArrayData(array("Title"=>$name,"Content"=>$val)));
$d->push(new ArrayData(array("Title"=>strtolower($key),"Content"=>$a)));
}
return $d;
}
}
:::yml
Image:
extensions:
- MyImage
### Form Upload
For usage on a website form, see `[api:FileField]`.
If you want to upload images within the CMS, see `[api:UploadField]`.
### Image Quality
To adjust the quality of the generated images when they are resized add the
following to your mysite/config/config.yml file:
:::yml
GDBackend:
default_quality: 90
# or
ImagickBackend:
default_quality: 90
The default value is 75.
By default SilverStripe image functions will not resample an image if no
cropping or resizing is taking place. You can tell SilverStripe to always to
always produce resampled output by adding this to your
mysite/config/config.yml file:
:::yml
Image:
force_resample: true
If you are intending to resample images with SilverStripe it is good practice
to upload high quality (minimal compression) images as these will produce
better results when resampled. Very high resolution images may cause GD to
crash so a good size for website images is around 2000px on the longest edge.
### Clearing Thumbnail Cache
Images are (like all other Files) synchronized with the SilverStripe database.
This syncing happens whenever you load the "Files & Images" interface,
and whenever you upload or modify an Image through SilverStripe.
If you encounter problems with images not appearing, or have mysteriously
disappeared, you can try manually flushing the image cache.
