I have a few photographers working under me ( well, not exactly under me, but I say it anyway just for illustration purpose), so they shoot a lot of photos, the problem is that they all store their photos on their hard disk, and I have no way to retrieve them unless I pass them an USB and ask them to fill it with their photos.

Very labor intensive and inefficient!

Is there any other better ( more automated) ways of doing this? For the fear of losing the resolution, I don't really favor a online-synch approach, because I think all the photos uploaded to any website will suffer a resolution loss, which is the last thing I want.

Is there a better idea?

Edit: Being artistic as they are, I can't guarantee that they all use PC and Windows; so the software must at least be able to run on Mac.
