[split] Coding Question

[ZiNgA BuRgA]

I'm guessing you want to have some slideshow of images at the top of the forumdisplay page, sourced from all? the threads in the forum which have images attached?
I don't think XThreads can do it unfortunately, since it still goes by how MyBB displays threads, so if you want two separate groups of stuff (slideshow and a threads list, kept in separate locations) you're probably out of luck there.

If you have a MyBB plugin which can display attached images, then I guess it could be possible to restrict attachment types/sizes for a specific forum.  Is this what you want?
