I tried a few things in Chrome on a Mac (OSX 10.9.1) and the site loaded and apparently behaved OK
Your work is wonderful, but I hope you're OK with all the images being easily lifted - it takes seconds to find the image name and then download it. Had you considered a very light watermark?
Given how large the images are - between a small and medium with Image Source's sizes - giving away a 1700 pixel (long edge) image unwatermarked might present issues for you. I realize that if anyone uses it, it's without a license and that you'd hope people wouldn't do that, but we've all had lots of issues with our work being lifted from web sites, so I thought I'd mention it.
