What is the best digital format and resolution for uploaded photos?
The photos can be .jpeg, .gif, .bmp of .tiff. Any resolution from 150-300 dpi is good. Many digital cameras shoot .jpegs at a resolution of 72. These are acceptable if the image is large enough. For example: a .jpeg at a resolution of 72 must be at least 31 x 23 inches or 2272 x 1704 pixels. Use the highest setting for resolution that your camera offers. If you are scanning your image to upload: scan it at 300dpi, actual size and save it as a RGB .jpeg or RGB .tiff.
