Position yourself in the dialog box in the forum, where you want the photo to appear.
In photobucket you have to upload whatever photo you want to use, using the "browse" options at the right side. When your photo is in place on that page you must select one of the formats under the photo. Choose the IMG option and HIGHLIGHT the address. The whole address will be longer than the 'opening' for it but just keep moving. Right click, choose copy, go back to your dialog box, right click, choose paste and it SHOULD appear! I'll keep checking back to see it it worked for you. I had to do a lot of fiddling around and got some help from some of the other contributors. It's not an intuitive setup so it does take some work. Hope this helps.
