Kevin,
In order to have text between pictures, you need to upload the pictures to some other location on the web. You can use The Gauge's gallery (button at the very top right of every page), or other sites like PhotoBucket or Flickr. The key to finding a good "outside" site is that they have to allow linking. If they don't you can create a link, ut all you will see is a red X or possibly a message saying external links not permitted.
Then you create your message, and use the html code to display the picture. It's usually something like [ img ]http://picturehostingsite.com/mypicture.jpg[ /img ]. (Note that there are no spaces in the tags, but I had to put them in so that it would show up for you to read.)
If you simply "attach" the pictures to your post via the "Manage attachment" button in the "advanced" composition window (i.e. not "quick reply"), you can add up to 5 pictures, but they will all be at the end of the post.
If you need more info, look for the "How to Post Pictures at The Gauge" thread in either GT or Photos forums.
