Limit attachment type per forum category ?

[AURFSCAN]

Hello everyone, I'm trying to work out how to only have certain attachment filetypes for individual forum categories.

eg.

forum1 - all attchment types
forum2 - all attchment types
forum3 - all attchment types
forum4 - all attchment types
forum5 - only images
forum1 - all attchment types
forum1 - all attchment types

Why is because I have front page slideshow that grabs images from forum5 which works
perfectly only problem is that if you attach a file other then an image it displays a blank slide,
which is understandable but annoying.

Q. how do I only allow images to be attached in forum5 but still retain all types in other forums?


Thanks in advance
Darren
