You have a couple of different options. If you have a photo editing software (like Photoshop), you can resize your image. I use a free software called IrfanView (Open your image in the software, then Image -> Resize/Resample). Or, you can load it up on a site like Photobucket, and then provide the link in your posting.

Hey Carrie,
I use Photobucket and that has solved the problem.
