Hosting for images with API?

Let's say I need to make a mold where the user selects the file to upload to the site, and the file is uploaded on ImageShack for example, and not my server.

I know that ImageShack has an API, but it gives links to the user, and I need these links were sent back to my server, ie:

user --> image hosting --> my website.


Tell me where to find such a service. Here's an example Loginza made very cool — have it in user's my site spec. the key, and through it my server requests data from Logins, and that gives him all the necessary information about users — here is the best solution.
