Thank you for your help, Joanna. It's weird because although some of the files are different sizes, it looks like it's inconsistent as to the upload issue. I'm trying to load a smaller file right now but it's taking a loooong time and says "waiting for garden.org". I was able to upload pics on FB and email no problem.
I'm not sure what the problem is but I don't want to clog up this thread with it. Joanna, I'll look into the issues that you've suggested and maybe start a thread in a more appropriate thread and link it here.
