Mary, unless you have come up with a solution, you could go to
www.fookes.com and download their free prgram "Easy Thumbnails".....I've been using it for years it's simple and allows you to size your photographs to just about any size you could want.......it needs to be simple for me to use it <grin>..........BTW. Enjoyed looking at you caricatures, very entertaining...thanks for sharing.
