<?php
/**
* A field that allows you to attach an image to a record from within a iframe - designed for use in AJAX forms where it
* is not possible to use {@link SimpleImageField}.
*
* <b>Usage</b>
*
* If you want to upload all assets from this field to a given folder you can define the folder in 2 ways. Either in
* the constructor or as a method on the field
*
* <code>
* $myField = new ImageField("myName", "Upload image below", null, null, null, "myFolder");
* </code>
*
* Will upload images into the assets/myFolder folder. If that folder does not exist it will create it for you. You can
* also define it as a method
*
* <code>
* $myField = new ImageField("myName");
* $myField->setFolderName('myFolder');
* </code>
*
* @deprecated 3.0 Use UploadField with $myField->getValidator()->setAllowedExtensions(array('jpg', 'gif', 'png'));
*
* @package forms
* @subpackage fields-files
