I think I'm getting it.
The pic;s are an email attachment and I open them in Adobe photo shop. I can rename them and save to my documents.
Why would I have to join or download some other software? When I try and "Add Imahe" on this rely for instance, it wants to know image URL and starts with http:\\ . . .??! I don't know how to do URL or create an http.
I upload pic's all the time on eBay or emails, but this has me befuddled.

This box with red X is what I get when using my feeble method. And what's the deal with "Avatar"?
