knepptune,
Try this to post pictures.
Save picture to someplace on your computer you can find it, I usually do it to the "Desktop" but any place should be fine.
Now when you are in the message box where you enter the text like where I'm doing this right now loo just above the text area for the "picture icon"
That is the one circled in red above. Click on it and it will let you insert a picture from "computer" or "URL". Click on the words "From Computer" Then on the "Select Files" at the bottom of the box. Now just find it on you computer and double click on it then on the "Upload File(s)". This should take you back to the text message box with a six diget number between the words "attach" in [xxx] brackets. You can add text below or above that as that is you picture. Then click on Post and your picture should be right there!
Takes ten times longer to try to explain it than to actually do it.
