I realize this probably isn't what you are looking for at the moment, but it is probably a simpler and easier solution in the long run.
Set up an account on Photobucket. It's free and at least when I did it, it was very simple. Photobucket is also very easy to use. Open up the page, click the download link, and either browse to where the pics are on your computer or, even better, open up the folder containing your picture and drag them right in to Photobucket. After you have them loaded up, whenever you look at your photobucket page, you will have links to choose from that you can use to post that current pic to a forum. I have a thumbnail link, an image ling, and a direct link which I use depending on what forum I'm visiting (some like different formats) and how many pictures I plan to post. In this case, I'll post up a random Galaxie pic from my photobucket account....
If I were on the old FE forum, this would be the text posted to display the same picture.
