The software that came with your
camera will usually have a program for reducing the file size.
Otherwise those of us on dial-up get
a little distressed.
Well one of Margie's photos at 500 dpi would
really distress most. It would be about 450 kb.
All web photos should be 72 dpi or less. Dpi is
dots per inch for printing. Your monitor can only reproduce the
maximum of 72, more is a waste.
Resize to about 7" x 6.5 or somewhere close at
72 dpi and you will be under 50 kb.
