Whenever I do work with a photo in
PS, it looks gorgeous in the program, and in the Mac application Preview. I can also upload them to ImageShack.us and they retain their quality.
When I upload it to Facebook, it looks blurry/shoddy. If I upload it to printing sites like Shutterfly, the site tells me the best size I could order is Wallet because the resolution isn't high enough.
What gives?
