Ok, I opened the photo, held my finger on it until "copy" appeared, then touch "copy."  Open this forum and in this reply box, touch, holding your finger on the screen till the word, "paste" appears.  Touch "paste" and the photo you copied will appear.

 I found the directions for posting photos HERE.
Cutting and pasting won't work.  You should be able to post from an iPad the same way as you post from a regular operating system if you photo is hosted so it can be linked.  Cutting and pasting the URL is harder on the iPad.

I accidently deleted the hyperlink.  The direcitons for adding photos can be found HERE

and again just in case
