Bob--
Looks to me as if you're attaching them just fine. If you don't do anything else, the pics end up at the end of the post, as you have seen.
To control where the pics go, first attach them just the way you have. Then, in your text, go to the pulldown menu above the smilies and choose Attached Image as Thumbnail. That'll insert some mumbo jumbo in your text. Go ahead and add text after it if you want, maybe some blank lines.
If you do this, the first pic you attached will show up where you put the first Attached Image as Thumbnail, and the second pic for the next.
Why not try modifying the Trammel post to try it out? Clicking the Modify button above your own post puts you back in the editor.
