Today I was bored, and I didn't know what to do. I was looking around my PC for some images when I remebered that I'd like to get an image viewer for almost all kind of images. The only program I know to be capable to read almost everything is ImageMagick. After some hours, I've got the first result, my new program can read every images supported by IM. Obviously, the window can be resized, and can also store my preferred window size for the next use. I think the program will have not too much apart the three important functionality "zoom +/-/reset" and maybe the "next/previous" functionality.
I'm still bored.
