No, I have no familiarity with Photoshop, unfortunately.
Edit: Man I am dumb. What I do have is a touch screen, so I might be able to swing even uglier but quick and dirty maps drawn "by hand" the way one would with an erasable map.
GIMP is free and layers are your friend. Even if you use only one layer for the map. Being able to move the characters around without erasing the underlying map is useful.
Nothing wrong with the game. I may have overestimated the amount of time I have to post; I usually do so at work but recently quite a few days I wasn't at work or was too busy. Sorry about that. I expect that after this weekend it'll be better.
Ah, okay. Just wanted to check in. Would be neglectful of me as a DM running an off the cuff game to not check in and see that everything is okay if there is a pause in play.
