Welcome to the forum Tryitagainsam,
Are You uploading from a computer or a smart phone? I use my computer and the only problem that I am having with the uploads is with the orientation of the photos themselves. I take the pics with my iPhone 4, transfer them to my laptop, view them with my viewer program (Paintshop Pro 8), rotate them to the proper orientation (they come in from the phone rotated differently than viewed on the phone), and upload to my post. One of the methods allows You to add commentary, the other, not. I have not tried to do them directly from the phone because, in the past, I have always had trouble with anything on the phone that uses a large amount of data.
I hope that (and I'm they will), someone with greater knowledge about these things, will help out.
