Just discovered I can create/respond to a thread on THR on my computer,(with its big screen and keyboard) do all the typing, go to my IPhone, (with its itsy bitsy screen) log into THR pick up my thread/respond, use the upload radio button, post a photo from my phones photo albums, to the thread/respond and post. One can even select thumbnail or full image while posting from the phone. Close out the phone, return to the computer and Viola, there it is. Neat if your intended photo doesn't reside on your computer, which in my case they don't.
