Upload Image Issues

I have been having issues uploading images to my menu on my restaurant’s website. While two of the menu items look how I would like them to look:

http://primetimetallahassee.com/menu/insalata-caprese/

Most look like this

http://primetimetallahassee.com/menu/king-cobb-salad/

and have broken links. Can someone please explain what I am doing wrong?

Thanks,
Madelynn
