While writing about why you should probably make time for Twitter and Facebook over on the ThriveWire blog, I searched for Creative Commons licensed photos on Flickr. Here’s some of the gems I found but didn’t end up using over there.
Bright & Colourful:

I just love the colour and simplicity in this. (justinknol, flickr)
In the Vintage & weird department:

Hi there,
Thank you for for using my photograph in this post!
Please attribute the photograph to Duncan Rawlinson and link to me @ http://www.TheLastMinuteBlog.com as per my request on all of my photos here:

Take care!
I really like the last photo here. I live in London and it’s not that easy to find a coffee shop with character but it sure looks like this one fits that bill.
The bike locked up outside and the bloke on the phone really add to the shot’s character. As the photographer noted (on the flickr page) it’s just a pity the photo is a little blown out.
Yeah, it is a shame but I felt the same way, so much character I still had to include it.
Love your website URL/business name. Very clever.
the thing that i like most about flicker is the resize feature*:;
