Some images not showing up in new campaign
I've been creating some new campaigns recently (D&D 5E) and I've been finding some instances where images I place in my campaign's /images folder aren't showing up.
Last week when I ran into it an image I manually copied to the location would not show under Images & Maps. Clicking the Folder button opened that folder and I'd see the image file there, but it wouldn't be in the list inside Fantasy Grounds. I figured maybe there was just something about the image file that FG didn't like, so I opened it in MS Paint, used the Windows 10 Snipping Tool to take a screenshot of it, then saved the new image to the location. That worked.
Tonight I'm having the same problem with a different image, but the above trick didn't work. I know FG knows the file is there, as if I try dragging the image from another location into FG I get an error indicating the file already exists. If I rename it to something else and drag it I get no error, but the image does not load.
Other images show up fine when I copy them in. I can make a copy of existing images and they show up right away, but this image just won't. I can attach the image, though it's part of a copyrighted work (a map of the northern Moonshaes). I cropped it from the top of the Moonshaes map at the Forgotten Realms wiki.
