Uploading then Serving Images on a Load Balanced Amazon AWS Setup

view story

http://serverfault.com – I am setting up a load balanced system on Amazon AWS. I will be uploading photos to my server and then reading the photos off the server from another device. Let's say I have Server-A and Server-B running on my load balancer. If I upload a photo and hit Server-A, then I am assuming I won't be able to see the photo on Server-B. What is the best way to handle this? Should I create Server-C to hold the photos and access Server-C from whichever server I hit with the load balancer? Then there is no load balancing on Server-C, so I would have to setup a backup server that copies the files from Se (HowTos)
