I am working in Pro CS3. It's a HP 1.8 with 2 gig of RAM. I keep importing still pictures in different projects (different pictures in different projects). They keep coming up black. They do recover or if you click on them enough they do come back that way. Is it a RAM issue or settings. I can't seem to find the solution.
As well as size, I have read that pictures created by a device that puts "extra" information in the file header won't work well... solution is the same as Jim gave, open in a known good photo editor and resave so the extra header information is stripped away
