Dave over at Chromasia doesn't take a photo a day - as I understand it, he may take a load but post them one at a time. For example, he's recently posted a load from his trip to London to meet other bloggers. He also has a choice of background - white/grey/black - but you being a web guru would know how that's done!
His pal's webby at
http://shotsphotography.co.uk/blog/ uses a neutral grey - a sort of PS default that supposed not to be distracting.
