Image Upload Helper

Installation

1. Upload the plugin to your blog.
2. Activate it.
3. Nothing happens.

This is a library. It doesn’t actually do anything by itself. To use it in a plugin:

1. Include this plugin (in its entirety) in a subdirectory of your plugin. It plays nice with other
   plugins; if a site has multiple plugins activated, each with its own copy of Image Upload Helper, only
   one will load.
2. require_once( 'image-upload-helper/image-upload-helper.php' );
3. Call image_upload_helper() wherever you want an upload dialog available.

The image_upload_helper() function takes an array of arguments to control exactly what the form
looks like.

• field_name – Required. The name of the form field that will be submitted. Defaults to
  « image-upload-helper ». Use this to customize the field to fit in with your form. By changing
  the field_name value, you can call image_upload_helper() as often as you like on each page.
• thumbnail_id – The attachment ID of the current value of the field.
• label – The label to use for the field. Defaults to « thumbnail image ». This will
  display as « Set thumbnail image » or « Remove thumbnail image » in the form, or « Use as
  thumbnail image » in the iframe dialog
• size – The size of the image you want displayed in the form. Defaults to « post-thumbnail ».
  If you want to display a custom size, make sure you register it.

When a form is submitted with an Image Upload Helper field, the field specified by the field_name argument
will contain the attachment ID of the selected image.
