Hi all, pretty new to this so i'm hoping you'll forgive a possibly newb question. I have purchased a digital map pack for Curse of Strahd from Mike Schleys website (not sure if i'm allowed to post the link but it's easy to find) - the site says it is "ideal for virtual tabletop". But no matter what i do i can't seem to get it to align to the grid in Roll20. i did have to resize the original image (it was a 61mb png file so i've shrunk that by a percentage and re-saved as a jpeg so it doesn't use as much space) but i was careful to maintain the aspect ratio. Anyone got any advice?
