It would appear that something has changed in the way smugmug is allowing linking and a lot of my images are suddenly (and frustratingly) broken. I’m hoping it’s maybe just a server issue and I won’t have to go through and manually fix everything. My apologies until it’s sorted out!
Edit: All fixed! Thankfully it was just the most recent 3-4 posts being messed up so it was easy to go through and fix… apparently my old way of linking images doesn’t work anymore with newer photos!
