Hotlinking from other site?
 

I am not sure if this is the right section, if not, mods please move the thread to appropriate section.

I run a photography community where plenty of users already have paid accounts with sites likhat?e flickr, pbase, smugmug etc. As we run the competition, users ask if they can link an image from their photo hosting to my pp gallery instead of uploading it again? This is completely legitimate hotlinking allowed by those sites and users.

Does PP have such a functionality? or how much time would it take to build something like t

No the image has to exist on the server to be used in Photopost so they must upload it.
