Graphic design and picture resources

On my trawls through the web for media services, medical illustrators, graphic design and medical (and other) images I have come across the following which I'm recording here mostly for me but I hope others find it useful too.

Creative Commons
Search.CreativeCommons - click on the tab you want, eg Flickr, type in what you want (when I just tried this they had a default search for flowers which demonstrates the system) and you'll be given a set of pictures that you can choose from. Were you to search for 'food processor' you'd find one of mine (Jodiepedia) which has been gratifyingly used on the web :)
http://search.creativecommons.org/

You can of course search both Flickr and Wikipedia (Wikimedia) databases directly but this global search is much quicker.

**********
I used to do some freelance blurb-ing (generating 30 word precis and title from about-to-be published manuscripts) for BioMedCentral which included a bit of picture accessing and tweaking. As such the following websites are for medical images rather than general graphics - I've not included login details (it's private). You will have to judge for yourself whether an image or photo can be used.
