I wonder if a case could be made to the devs that this would be a good way to optimize load times, band-with usage, etc. It would need some tweaks.... Lets say that the gm had the ability to open up a specific editor for the map layer. In that editor all the information on the location, size etc of all the assets on the map layer would be retained, but when you close that editor(or maybe you have to tell it specifically to save a new snapshot) it saves a render of the map layer in whatever format roll20 prefers to use. Then whenever you aren't editing the map layer specifically it is just 1(or even several depending on file size) large .jpg or whatever format roll20 likes to use. The main benefit would be reduced bandwidth, at the cost of slightly higher storage. A secondary benefit would be the ability to have more detailed maps for campaigns without slowing down to a crawl. Another benefit would be that you could have access to all of roll20's assets for making your over-sized maps. Currently there are some assets I would like to use and have purchased, but I can't download them because they are only licensed for use in roll20. That means I either have to accept terrible load time when I make a large dungeon with them, and maybe crash someones computer, or use other assets in gimp(or another similar program) to make my maps. That kinda makes me wish I hadn't spent the money on that particular map tile pack. Its a beautiful tile pack, but its use is too limited. If I could save a render of the map layer and use that render in game, that would be awesome. EDIT= I do realize it would cause a loss of the ability to move things on the map layer during the game, but I think that most GM's already use the map layer for things that aren't supposed to be moved much if at all, and I am sure that a lot of them would trade the flexibility of the current system for the benefits of the proposed system.= EDIT
