Xoops has an IBF module done by Koudanshi, you would probably need an addin of some sort, perhaps a gallery and download module. I have seen a couple of these sites using IBF, one in particular, but I think they did their own hack.
Mr Koudinshi is a hack specialist, if you post on his site he might just help you.

xoops also has some powerful gallery modules like xcgallery (coppermine) etc which allow upload and download, and user galleries
