File Size: No larger than 700 K.
Format: .jpg is preferred. .tif format is acceptable, also.
Resolution: No more than 150 dpi. No less than 72 dpi.
You can usually select the dpi when downloading digital photos. 300 dpi
is 'way too high and will make the file size far too large. The file size
shrinks as the dpi is reduced.
Dimensions: About 4" x 5" usually works well, but file
size is more important than dimension.
