Is this the image you wanted to post Sandra?
Ah, I see what you might have done now. Did you copy and paste the image?
If so, what you need to do is right click on the image you want to copy, then click open image in new tab, then copy the URL, come back here and click open the square box with the sun and mountains, then click the link button (looks like a chain link) and paste the URL into the box with HTTP written in it, then click Insert.
Sandra, as I don't know how competent you are on a computer I've written out the instructions in the simplest way possible.
