My Product Pictures Are All Screwed Up

[seannyberg]

Hi everyone, I am new to Shopify and creating my first store when I came across a problem I cannot fix. My main product image is fine, but the other images that go with it are much bigger than I wanted, and I have to scroll down to see them all. Here is the product page for my store, and I zoomed out so the other product images were visible.

As you can see my main product image is fine, but the other ones are all way to big and not nicely organized below.

I have already tried resizing the pictures but that just made it worse. Its weird because they should automatically all fit below in a nice line so I don't know what the problem is. I also tried  looking at the code but am lost now. Any help would be much appreciated!
