Concept: Flickr, PhotoBucket, Picasso, etc integration

You would have to review the term of use for all those photo share websites to see if you are allowed to use them externally (hitlink to them).

Flickr for example does allow you to hitlink to an image, but it demands that a link is placed to the original photo page on flikcr.com for every image. So if you want to use this url as an img: https://c2.staticflickr.com/2/1715/24150...4a55_c.jpg you would have to place a link to https://www.flickr.com/photos/altreize2/24150085542/.

Plus they don't allow you to use more then 30 hotlinked images on a single webpage for bandwidth related reasons.

Link back to Flickr when you post your Flickr content elsewhere. Flickr makes it possible to post content hosted on Flickr to other web sites. Pages on other web sites that display content hosted on flickr.com must provide a link from each photo or video back to its page on Flickr. This provides a way to get more information about the content and the photographer.

It's a nice idea but I dont know how feasible it is. If your websites becomes a success you don't want to be that vulnerable that an external factor (like a decision from flickr not to support you hotlinking to them anymore) that would kill your business model...

Yea I believe you and Avenirer are correct. It was just a thought though. I wouldn't have any problem putting link back of even  watermark  "provided by Flickr" or other on the link. But looking deeper it seems to be much more work and possiblities of security leaks. Not worth it at this point. Maybe at a lter point?
