In reply to Hand of Destiny (msg # 996):
I use this site:
https://imgbb.com/, as do some other DMs on RPOL, to upload maps.
It's free, and you can upload a fair number of images, and then link to them from an RPOL post.
In some my other games, I map on graph paper, scan, crop in photoshop, upload to ImgBB, and then link from RPOL. You could simply create a Map thread and change the link as needed.
Works for me, not sure if you have the time!
