A simple, easy-to-use program for converting multiple image files from one format to another. Supports the following image formats: BMP, EMF, EXIF, GIF, JPG/JPEG, PNG, TIF/TIFF, and WMF.
I'm Linux-based, but when I try running this on a VirtualBox'ed-XP, I get a "...is not a valid Win32 application" - kinda bizarre! It runs flawlessly on Wine 1.6, but when converting PNG screen-grabs from Ubuntu 10.04, all the images end up as low-res black & whites! Sob.
