Yeah, I'm dropping them onto the existing thumbnails in one of the photo galleries from the design gallery. I tried adjusting them manually but it takes a long time when you have a lot of photos and it kinda defeats the purpose a little bit of using a ready made photo gallery. Also the popup images lose their original aspect if I resize all the thumbnails down to a uniform size. I don't mind the thumbnails being squashed a bit but ideally I'd like the popup images to maintain original aspect ratio and not be cropped. I think the only way to do this is to have thumbnails that are not uniform in size, which I was trying to avoid, but maybe it's the only way to go.
