Not the best, but still a decent transparent Shutterstock.com logo.

From www.boston.com/bigpicture/ :The Big Picture is a photo blog for the Boston Globe/boston.com, entries are posted every Monday, Wednesday and Friday by Alan Taylor. Great Site that doesn't really have a logo so I just threw one together.

FotoTV.com is a website showing films about all facets of photography from the technical to the artistic.

The unique WebTV site, catering to both knowledgeable professionals and photo enthusiasts, presents a broad range of filmed material via an interesting mixture of web based workshops, tutorials and interviews. Acclaimed photographers Nobuyoshi Araki, Elliot Erwitt and Ed Ruscha are some of the enticing personalities presented in the filmed material.

NASA image access. Pictures of planets, comets, galaxies etc. I'm calling it opaque (there's just a little transparency feathered around the edges).

Transparent logo with a woman whose breasts have been tattooed to resemble soccer balls (or "footballs" as you say over there in Europe). The logo itself just shows a bit of cleavage, not a big deal. But the theme is nudity at public sporting events, so the photos are mostly work-unsafe.

White, opaque logo. Incredible photography of tiny things. Dennis Kunkel.
