[Clipart] where are the PNG examples at the website?

[Jeremy C. Reed]

I was attempting to search the openclipart.org website to find some 
clipart, but didn't see any examples.

For example:

http://openclipart.org/media/files/zeimusu/2749
and
http://openclipart.org/media/files/johnny_automatic/1125

I see no example PNG images. (Luckily the browser I am using does display 
the SVG file when I click the download link, but that is slower to view 
images one at a time.)

Before there used to be webpages that showed thumbnails of many images 
making it easy to browse. Is that still available? What URL?
