How do image hosting sites make money?

[redrory]

I'm making one

It's not finished yet, but you can see beta at www.pixfolder.com.

Bit Off Topic:
But pixfolder.com is looking quite good. Keep us updating
For some major traffic, try and get it on Techcrunch

I like the look, it has the web 2.0 feel and even the smell

I found a great script for an image hosting site. The real way they make money is becuase when you upload a picture you are given a link to show the image to others. The page that they see contaions the same image and is packed with ads.

Having said that, it is not worth it. Unless you have a design or photography community niche then a general image upload will not get enough traffic becuase there are thousands of them.
