Carta online resources
Everyone knows that when it comes to maps and photographs for learning Tanach- Carta is the master! their material can be kind of expensive though. Carta has now digitized all of its articles maps and pictures and opened it up to the public! This is huge! There is a monthly fee after the first free month. I use it all the time for my shiurim and guiding aids (mainly for the maps and pictures). More info available here.
