There are no specific dimensions for CD case covers.... We decided that they should stay at their original dimensions when scanned.... Just make sure that they are 300dpi and clean....

I think they should be around 1400 x 1400 for the front and for the back it depends on the system(PS1, Dreamcast, etc...). Just look at the dimensions in cm and you'll know if they'll be big enough...

Besides everything I currently work on I always put in my folder so no double work is done by me and others.... I'm currently working on around 40 or so covers uploading wise and I hope I'll be finished in a few days....
