Hack/Modification suggestions ?

[athloni]

I run an auto forum and I would like each member to have a gallery of his/her car pictures, as well as an enhanced profile page where they could show them off in thumbnail or larger format.

I know it is possible and the hacks are out there, I am wondering what the best combination of modifications to do this would be, from your experience.

Any other ideas on how I could expand this idea would be great!

TIA
