Was searching for a free image viewer that supported this and discovered this:
Author seems very active.
Edit:
giving it a go, some other nice perks:
-super fast
-can run multiple instances
-can preview tiling
-can be always on top
-has non-destructive editing

Thanks for the link.
In lieu of a Git account, here are some issues I've come across after using it for a bit:
-I get flickering borders when using the tiling preview
-Related to drag and drop; it would be great to be able to spawn a clone or new window from the current one (and with hotkey)
-I might be missing something, but I can't see anywhere info on the bit depth (bpc)?
lol, don't give me ideas!
