Here is what you can do:
Create a photobucket.com account (very easy)
If you arent automatically re-directed to the "albums & upload page:, click on the link to go there. (its on second bar all the way to the left)
Under "Upload Images & Video", click "Chose a File"
Once you've uploaded the file it'll take you to a page where you can name the picture. Click "save and continue"
The picture will then show up mid-page.
Hold your mouse over the image and you'll see a bunch of options appear. Click in the IMG Code area. It will automatically copy that code.
You can then post that code on the forum. When you click Preview or Submit you'll see the photo appear.
