IMHO, picture galleries are not really closely tied to discussion forums so it's not high on the feature list.
That said, jforum does handle uploaded pictures in a fairly nice manner already. When you attach and image, it can make a "thumbnail" (which can be large) that gets displayed above the attachment details. Clicking on the thumbnail shows the full picture.
So, you can have a
thread or a post that has a gallery like feel to it.
It might be possible to tweak the templates and code to make it more gallery like... FWIW, I suspect that the easiest way to do this would be to run a second instance of jForum in "gallery" mode.
Submissions of new features via jira are always welcome.
