Cliff--
You'll undoubtedly get more knowledgeable advice from some of the computer heavies on TBN, but I think the only way to get large-file-size pictures to a postable size is to open them in a photo editor and then "save as" a copy with different parameters. In MS PictureIt, which is definitely Photoediting for Dummies, click on "options" and you can dumb the picture down (the smaller the numbers the smaller the file). It also has a "save for the web" option which turns an 800k picture into a 24k picture which is still intelligible onscreen. In other editors the process is more complicated, but in the handful that I've used it always involves file/save functions. If you don't have an editor, I'm sure there is a shareware/freeware way to do this that someone can refer you to. Good luck!
