Hi Dale, there are free resizing programs on the internet. Usually the instructions are pretty easy. You have to either change the picture size or the pixel size (I think) to decrease the file size. Resave with a different name so you don't overwrite the file.
Something I sometimes do is upload the pic in MS Paint and resize it. Have not always had luck with that method - but I'm sure the problem was sitting in the chair (not the PC).
