anyone tell me where? Only want to pay a couple of quid - or less if possible.

Search flickr and filter out non-Creative commons licenced images?

i tried that.. im not sitting through millions of sh*t. I dont really want to see peoples piled up  junk around a computer desk.

There's no such thing as good + cheap when it comes to stock photos. Just cough up on one of the two big boys reserves:

http://www.bigstockphoto.com/

For more specialist stuff I've found it's a better use of time to just do your own graphics than spend ages trawling through photo and clipart sites, but when it comes down to it I've used bigstockphoto for lots of generic things over the past few years and it's quite good and shouldn't break the bank.
