This is interesting topic...
Company I work for spent several months to custom program a "web-service" to serve pictures on several sites. Idea is that we can put in the "web-service" a set of pictures of 5000 pix and it will be displayed on several sites as we like (resized, re-selected,...). The concept was created to make a part of cross content on several sites which would all have their part of own exclusive content also, it was also done to save place because when you have hundreds of thousand pics, better to have them once that one time per site.
But I am far from satisfied by the result because for obvious reasons, I cannot brand the pictures them-selves... and all technical solutions to brand the picture when they are downloaded by the user are really slow...
So I will go to have a look at the software you advise
