Please help me get some photos accepted! I'm using an Acerscan 620UT to scan 4 x 6 photos at 600 dpi. They are of proper size (1024x768) and format (jpg). I'm using Adobe Photoshop 5.0 and sending as highest quality. I've tried the same photo untouched, and various different manipulations using photoshop. Also what dpi should I use to scan slides to upload? Any help from you experts out there?
