Hi Carol and welcome to the board. :rah:
Your pictures are not showing up. I'm guessing that you have browsed for and selected your photographs, but not clicked 'Attach'.
When you change the size of your image, make the longest side about 700 pixels and then it should be big enough to see. If your camera takes very large images (as mine does), you might need to reduce the quality of the jpeg a little as well, but don't go below 91% or the resolution will be too small for us to see detail.
