Judy, when you click on the photo you want to use from the DB, it will enlarge and at the top you'll see its 'vital statistics'.
Look at the bottom line there and you'll see "ATP BB code . . ."
Copy that code, including the beginning and ending brackets.
Then Paste it into your article.
Easy as that!
Once done, then Preview your article to see if it's just the way you want it.
Hope this helps!
