For the last post What do I do with an image file? Open it with disk copy if you have a cd burner you could burn it but I suspect you don't. It is proably a copy of a cd most ofen but can be floppy also. Get disk copy from apple if you dont have it. It's free The other 2 posts say limewire docs. cant say Ive seen one a lot of the sit files dont apper to be real stuffit files, but stuffit6.5 opens them fine just the same. maybe you just need to upgade your software.
