store image url on database

Hello! I like your community and glad to be part of it! My question:

Is there any plugin or (easy:_)) way that enables the visitors of my site to upload photos directly to the database and not send them to my mail?
Furthermore if this is hard to do is there any way for the url only to be stored on the database when a visitor uploads a photo? (lets say with Contact Form 7 or so…)

Thanks for your help anyway! I need the answer faaaaaast :_)))))))
