Thanks for the info. After reading the FAQ before I sent this message initially, I figured that's what I might have to do, but wanted to be sure there wasn't an easier way. The following is in the FAQ and the reason for the question:
"How do I add an image to a post?
If you have uploaded an image as an attachment, you can click the arrow next to the 'Attachment Icon' and select it from the list. This will be inserted into your post and can be located where you want it displayed."
Thanks again!
