-<?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'));
- *
