Image Hosting Script

Guys,

Does anyone have an image hosting script that I can use freely on my site and customise a little?

I need something that will allow people to upload images with a max file size of my cossing and then give them a unique url for their image.

It also needs to have an admin back end to it that will allow me to set variables such as image types allowed as well as file sizes etc. Also a preview of each image uploaded and a delete button. IP logging would be a bonus as well just incase someone uploads something illegal.


Can anyone help with something like this?


EDIT: I will not be using this to make money by the way, just as a place to allow my sites visitors to upload avatars and stuff.
