Adobe Photoshop and Elements plugins
In general, each plugin can be used with all versions of Photoshop (3.0-7.0, CS, CS2), under Mac OS X, 9 and earlier, and Windows.
Should also work with other compatible programs such as Elements, AfterEffects, Premiere, PhotoDeluxe, Corel PhotoPaint, Paint Shop Pro, Fireworks, Painter, Photo Impact etc.
1. ICOBundle utilityCombines multiple ICO images (e.g. created by the above plugin) into a single ICO file. More info
Also of interest, to Linux/UNIX/OS X users, may be the icoutils package (extract, convert icons etc).
2. Photoshop file (PSD) Extract/Recover toolThis plugin lets you grab image layers from any PSD/PSB file. It's faster than opening the whole PSD in Photoshop, if you just want a layer. Most importantly, it can usually recover image layers from corrupted PSD files that Photoshop won't open (if Photoshop opens with damage, this plugin recovers a more intact image). Beta version.
