MyPictr.com

A quick plug for MyPictr.com, which takes a pictr—I mean picture*—and scales and crops it for various social-networking sites. LibraryThing actually doesn't have set sizes. (Many sites require small squares, which appear all over the site in lieu of names, which, as we all know, involve those tricky letters things.**) Even so an easy-to-use scale-and-crop service is welcome. (Hat tip: Steve Cohen)

*Creative site; lemming name.
**The chosen picture, smiling college student with beer about to spill is telling.
