I just finished a simple but powerful module that really improves the quality of thumbnails and preview images. It adds a touch of sharpening and converts all derivative images to a color profile of your choice (such as sRGB). This is especially useful if you're using "professional" color profiles such as AdobeRGB since colors often look faded with those profiles if the browser isn't color profile aware.
I know people have been doing sharpening and stuff like this before in Drupal, but I don't think there is a module that does it for you, without patches... until now! All you need besides image.module is ImageMagick.
I haven't uploaded this to CVS yet, 'cause I was hoping that some of you would like to try it out and give me some feedback. Bad spelling, bad name, fundamental flaws? Good stuff? Let me know!
