Are we on different websites? I used the search box to search "cat" and the "enter" key doesn't work to perform a search, I have to mouse over and click the magnifying glass to get it to work. It takes about 45 seconds to load about 2 screens of cat pictures. I have to scroll down and then click "Show more" to get some more. There's no indication of how many times I have to click "Show more" to get all the cat pictures. Once I click "Show more" it appears that nothing is happening, but about 30-45 seconds later the screen starts blipping and then another couple of screens of cats start popping into view. Clicking on an image takes another 30 seconds and then it brings you to a slightly bigger view, and then clicking it again shows another slightly bigger view but trapped into some weird-scrolling viewer with 3 layers of vertical scrollbars. The back button is also broken, having to click it multiple times to escape the single-image screen.

I think a simple pager with a fixed number of images on each page would have been a much better experience. It would also let me link to specific pages so I could share the page I'm viewing.

EDIT: I'm leaving the post above but right after submitting it I felt regret because it sounds really harsh and I didn't mean it that way. I love the fact that the images were released and I hope government and private institutions continue to do this. I have very minor gripes about the ui but that shouldn't take away from the accomplishment.
