DXMage said: mmmm yeah I scanned them at 600 DPI That's actually a good practice at the start, but you need to reduce for using them on the web. The DPI you have now is suitable for printing (too high for web screen). Since you scanned on very high resolution, you've got the option of "zooming in" really far and still seeing clarity on your maps. It's for the best to start with that. As stated in the thread, chopping into districts / sections is one likely option, however you can also try reducing the DPI or the pixel dimensions by a lot (same effect, 2 ways of doing it, DPI or dimensions), and upload the much smaller web-sized version (that should turn out something like 2300x1500 would still be quite large on screen, you'd be able to zoom and scroll around on the roll20 desktop with that). What I'm trying to say is before you go through all the "chopping" method, you might want to try putting the whole big map on 1 screen and just see how it functions for you, but do this at about 1/6th the size of your original scans. You will probably end up wanting to "chop" anyway, but you can have 1 page in your Roll20 that is an "overview map", or use this to see how a big map would work. Just not so big as your original scan. :)
