Redesign (Score 2)

That huge bandwidth is a major load requirement of the project. That bandwidth is going to cost you or your client too much money. I think you should simply look into separating the functionality so you can do the analysis on customer site, and you only "get"(pulling from db, webservice, or a rss feed) the analysis results right there on customer's site, and the rest of your application sit where it is now. From the sounds of it the images are first saved somewhere on customer's network, so perhaps it is not much of a stretch to install your analysis app right there?
