Help!

All the photos are being cut off. How do I fix this? Oh no. I think I might know what I need to do. I just realized there's an add photo button, and that if you use it to upload images then it will resize them for you. This may take a while, though, provided it actually works. (But if someone has an actual answer, please tell me. Like, is there an easy html way to just scale down the pictures?)

ETA: fixed.
