Well Carl, I am not too tech savvy. I have an iPad with photos but have never had any luck posting. A real PITA! Sorry......
I use an iPad as well. Posting a pic has gotten better than it used to. When you're in the reply window:
* Select Manage Attachements. A new window will open.
* Select Choose File, then Photo Library
* Select the album, then the picture
* Select Upload. Once the pic uploads (wait for the file to appear under the Choose File buttons) close the window. To close the window pick the little "x" to close the tab, selecting the "Close Window" does nothing. Another quirk of Apple.
Now your back to the reply window. If you've already typed your comments then just select Submit Reply. Once you do it you'll see it's easy. No worries if you don't want to, just though it would be cool to see it.
I'm posting pics in case you want to try it or if any other iPad user wants to know how.
