They have had that changed for quite a while.
When you click on a photo in your album and it brings up a page with the just that photo on the page, look to the left in the side bar.
You'll see a box titled "Share this image". Just click on the window to the right of "IMG Code", and it copies the actual code to your clipboard. Then click paste in your forum message and viola, the link to your photo is pasted.
After they changed it all up, it took me a while to figure it out. I've always said there is absolutely nothing "intuitive" about the way this stuff works, because programmers don't think anything like the older generation. We're not even on the same wave length.
