This module provides additional tokens for image fields. For each image style available, a token [node:field_image_field:style_name] will be provided. It is also possible to get image properties like width or height by using tokens like [node:field_image_field:style_name:height].
Copy module to sites/all/modules folder and activate ImageCache Token module in admin panel.
No module configuration needed.
I've observed that after you create new image style it might not appear immediately in available tokens list. If this is a case, you will need to reset cache at Performance page.
Damien McKenna has joined as a co-maintainer and will soon be working on a stable release. The module was initially created by Pavel A. Karoukin and includes many comments and patches from Drupal community.
