ImageTag_Hotfix This hotfix makes it so that all Image (and derived) object use PIL to resize when you use the tag method with integer (non-%) height and/or width parameters. This way, stuff like the PhotoAlbum will behave (not give you a page full of full-image thumbnails). This version should be cache aware, it's recommended for big sites to associate these with a RAMcache to cut down on PIL usage- thought it's pretty fast. It also steals the RESPONSE.set_header code from Image so the thumbs are cached on the clients. Since it's a hotfix it's easy to try it and see if it's working for you, and remove it if not. It does not modify any of your images - it generates the thumbs on the fly and only stores them in a RAMcache if you have one set up. Check the README.txt for sage advice on getting PIL to work :) here: http://www.zope.org/Members/bowerymarc/ImageTag_Hotfix
