[Clipart] where to browse clipart images? (looking for VPN diagrams)

[Jeremy C. Reed]

I am looking for clipart images. There used to be an OpenClipart website 
where I could view many images at a time.

I can browse by tags, but I need to see the images. Do I have to look at 
them one at a time? (I have near 100 in the first category to look at so 
this will be very time consuming.)

I am making some VPN (virtual private network) diagrams. So I need to look 
at tunnels, pipes, internet clouds, laptops, computers, etc. Or if you 
know of any public domain VPN clipart, please let me know.
