This time around, I'm highlighting some nice picture sites.
The Astronomy Picture of the Day (here's the feed) can have some pretty breathtaking shots. But note that the feed only has a tiny thumbnail; you have to go to the site to get the full post where you'll get a better size picture and an explanation.
Botany Photo of the Day (here's the feed). Another picture of the day, but this time guaranteed to be more terrestrial. This is a full feed and often includes multiple pictures and detailed, but rather scientific, notes.
Shorpy Historic Photo Archive (here's the feed). The subtitle of "Best Pix on the Net" has been replaced by "Vintage Fine Art Prints", but I prefer the other tagline of "Always Something Interesting." All of these are true. The feed is a full feed, but if you got to the site, you'll also be able to see the really big scans. Of course if when you want to sell prints, 2000 x 2000 (and larger) sized pictures are a must. You can easily spend a bunch of time "catching up" with all of the great pcitures here.
The Randomness Manifesto (here's the feed). Jeff used to call this "The Roving Medievalist" but has since changed the name as the scope has broadened. Many of the pictures are scans of medieval art and manuscripts, but you'll also find more recent prints as well as photos of interesting places (mostly sacred). There haven't been any for quite a while, but Jeff has had a few rants in the past. Ignore them and enjoy the pictures.
Orbis Catholicus Secundus (here's the feed). JP Sonnen puts lots of nice pictures from Rome here. He manages to get some really nice pictures while out an about in the eternal city.That's it for today. (Shoot, it's tomorrow now.) Time for bed.
