MoundMaster,
When you are typing your post, click the icon that is 2nd from the right, directly above the space where you are typing. (It looks like a tiny picture of trees and sky.)
This will open a little dialog box that asks you for the URL of the image you want to add to your post. The image (JPG, GIF, etc.) needs to exist on a server somewhere - you can't use this to upload an image from your computer.
Otherwise you can add the image manually by putting the tag:
[IMG]
followed immediately by the URL of the image,
and then end with the tag
[/IMG]
But don't put the tags on separate lines as I did above - put this all on one line with no spaces.
