Glad to help! What happened to your pics has happened to me a number of times. If you have multiple pics in a single post, the forum software creates a simplified code for all of them. The src" and ">, found before and after the second url in your post which didn't produce a pic is part of that code. Then if you go back in and edit or change something it screws up that code, and you usually get only the pic you edited or changed.
When you do an edit of a post with multiple pics you must be sure to clean all that extra coding out from your post so it looks like it did when you created it the first time. Maybe someone who understands the coding will be able to better explain this phenomenon, and offer a better solution.
