<font color="blue"> If that does not make the file okay for posting here, then go in and lower the DPI until you get below 100K or 100,000 bytes. Simply resizing the pic enough to post will make for a very small picture. </font>
Lowering the DPI is resizing.
Resize your photo to have the longest side around 600-700 and then play with the compression setting until you get the filesize under 100K. This should make a decent picture for viewing on screen.
