Maybe you could find a way to work around this without deleting your gallery! I, too, am distressed by the uneven look of a gallery page. What I started doing after the big switch was to make thumbnails that are all 500 x 500. You could have a couple of satisfying, lovely OCD days making new thumbs for your images! LOL!

What I'm doing isn't perfect, but it's close enough for me for now. Take a look at what I've done with the thumbs in my gallery the last couple weeks, and see if it gives you any ideas for ways to make this work better for you. I would hate to see you delete your whole gallery!
