This week I had a look around Flickr. I have always found it to be a good website, but sometimes you have to trawl through a bit of junk to find the kind of picture you are looking for. The photo I've posted is of a street in Japan. I didn't have any real reason for choosing it, just liked the look of it.
I think image sharing websites can definitely be useful for libraries! They can share ideas through photos, check out what other libraries are doing and get inspiration for displays. And also maybe ideas of what not to do, in the case of some... interesting library signs.
