I am looking for photo hosting

Hello.
I have a website. On it, users post pictures. I want to use some well-known image hosting, such as flickr, or picasa. But I want the service to give an opportunity to integrate into the site imperceptibly for the user, preferably on java-script, and not on the server-side. That is, provided the ability to upload and view photos on my site. Rutube works very well for video ( js-api ). But I can't pick up photo hosting. Advise plz.
