Same here when I tried it just now - 'More results' at the bottom of the 1st page got more pages to scroll down to from the 1st page. I'd noticed it before, but hoped it was a temporary glitch. I found the old system, with a web page per page (of lots of images) clearer and easier to navigate.
If smaller pages are more popular, fair enough; but there's something funny going on with the number of results. My search got about 5,370, apparently. 'More results' made it 45 pages (and that was all I could get). So about 120 images per page? No, just 18. Where did the other 4,560 results go?
