Here's how I did it. Find an image in Google or somewhere on the net. Copy the web address (URL) for that image--the one that begins with http.SURE. just because you know how to post and won't share the knowlege, pictures that is. Get it so that I can use I post it and other things too. Don't just hurt my feeling (I only have one) by posting and not telling me how.
In your post, click Img from the list above. Paste the web address in after that, and then click Img again.
A piglet could do it.
