First, before I continue this mission, a shout out to Aaron Nimocks. Of course he exists, but it really is his name! A quick search revealed several websites of his. Parsimony. He was able to solve my arcane request with about twenty characters. Yeah it comes easier for him–I mean, he learned how to do it–than for say, me, but he still spent considerable time on my forum request. He came up with two solutions!
So back to the picture thing… this seems to be wrapping but not quite enough. Fixed: there’s an adjustment thing in the advanced settings.
