Thankyou OncTech, just what I was looking for.

leo315: .cbr and .cbz are the universal comic format, and are very simple to create. just add your picture files (can be .jpg, .bmp or .png) to a folder, making sure that they are ordered by number or alphabetically in the order you want them presented, then compress the folder as a zip, or as a rar. if you made a zip, simply rename the file extension to .cbz; if you made a rar then rename to .cbr
