I've recently noticed that the quality of images in Safari have dropped in resolution. I have downloaded Firefox and tried this application and this has the same problem. I looks like a Mac OS-X setting issue. I was testing what the cmd-F10, CTRL-F9 etc and other combinations do when the quality shifted. I have a MacBook Pro running Leopard (4 GB, 2.5 Ghz). Images in all other applications look fine.
