Thank you so much for spelling that out for me, Brad! It is much appreciated. I’m not a web developer and I get over my head pretty quickly - that’s one reason I chose RapidWeaver, but when things get tricky, I get in trouble quickly.
I think I had two primary problems - (1) my main photo solution was a warehoused gallery stack that did not upgrade to RW6 and (2) my Stacks 3.0 plugin did not update after I had initialized and opened it.
Hopefully this is the end of the strange image problem I was having.
Thanks,
Dan
