I have a number of map tiles stored in my Google Drive which can't be uploaded to Roll20 because they take up too much space as a collection (and I'd have to delete other tile sets to use the current one), and on top of that, there are some individual files too large to upload in the first place (even with a paid account). Since Roll20's art library doesn't seem to have a problem pulling in image search results from the web, why can't I give permission to connect to my Google account and access my images?
