Usage
*
* 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
*
*
* $myField = new ImageField("myName", "Upload image below", null, null, null, "myFolder");
*
*
* 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
*
*
* $myField = new ImageField("myName");
* $myField->setFolderName('myFolder');
*
*
* @package forms
* @subpackage fields-files
