Keith, I take it there is no configuration to get the icon/thumbnails working? I am able to require RMagick from script/console and act\_as\_attachment tests run (some about deleting fail, but others that deal with creating thumbnails pass). But when I upload an image in radiant, the extension only moves the original image but doesn’t create the other sizes. Any tests yet? I’ll try to work on some later tonight. dm ---

Does acts\_as\_attachment create the database entries for the other images (icon, thumbnail and normal)? The way it works is that it creates a “master” image in the db and then the thumbnails are children of that. Be sure you have ImageMagick properly installed, it is a real pain to get it going. Hivelogic has a good tutorial if you are on a mac, although it should help in any case. I should probably include some sort of configuration for RMagick. It basically doesn’t work on Textdrive due to memory limits, so it would be nice to shut it on and off. I think Mephisto has something like this. I should have some time tonight to get some tests going. Keith B. removed\_email\_address@domain.invalid Tel: +49-7731-7983830
