Download or Transfer Map you made on roll20

I was wondering if there was a way to save a map i made pretty much square by square so i have a copy outside of roll20 or can send it to a friend?

A friend of mine did this on a campaign he created. After he had put together hundreds of resources, he realized the lag this was causing. The only solution when dealing with that many parts is to turn off the grid display and do a series of screen captures, then stitch them together outside the gaem with graphics editing software. The good news is that if you are handy with Photoshop or the GIMP, this isn't hard to do. Just make sure you don't zoom in or out during the screen grabs.
