I scrolled down and still couldn't see the checkboxes under the last row. Maybe it also doesn't work on Firefox, because as trivial as it is to make a site that works everywhere no one does. Normally this frustrates me, but if that's the case here it kind of makes sense.

The checkboxes are actually above all of the images.

I tried scrolling down, realized I couldn't, then scrolled up to find the unfilled row at the top...

I did exactly that as well. I’m also happy that there appear to be several different captchas, as others mentioned ones I didn’t see. The best one I clicked through was “select every picture with glasses” and every picture had either eyeglasses, drinking glasses or panes of glass.

I’m pretty sure the top row of check boxes doesn’t appear until you scroll back up.

facepalm this is even better.
