It's a shame you only got 1 reply here
I wanted to open a similar topic, but with a little bit different mindset. I'm starting a blog and there will be a few categories where I can't just put the product's image up(the posts that are not reviews). For these we need stock photos. Flickr is a good idea.. But if you want to play nice and not to worry about copyright violations, it's better to be safe than sorry. Make sure the license is right. People who upload to flickr may share great photos but those are not for you to take them and up them to your blog unless noted. In some cases attribution is necessary which is good but hurts the blog's image a little bit, no? That's just my opinion.
The reason why you sometimes can't grab a photo from flickr is that they put a transparent layer above the image so a 1x1 transparent gif or a htm file gets saved. They probably have a good reason why they don't want you download that pic. Sometimes I need them for personal use. You can still grab it, easiest method is if you have Google Chrome then you right click and inspect above the picture. You can remove the invisible layer (spaceball class div) and hit delete node in the menu, then you'll be able to save the image. In other browsers you need plugin: FF - firebug, IE - developer toolbar. Not to be used for shady puposes though!
Anyway, why do you look for free stuff? What size do you need these? I need them as a post picture that is never bigger than 0.2MP! (like 600x300 or 300x600 stuff like that) Most sites offer these smallest versions for like $1? And you get a good shot in return with (really) advanced search and whatnot.
My only problem is I fail at searching. I need some attractive women shots and the like, but I also don't want my blog images screaming 'Stock photoooos here!'. Sexis does kinda good I can't always tell if that's a stock photo they are using. Sometimes I look it up with tineye reverse image search and I can't find anything which means it's good cause it's a unique pic.
Anyway let me help you while I'm at it!
link This searches on major free provider sites and you can check licenses and there is a great search method. It also does flickr, sxc through wikimedia. I find that most of the results are inferior to the paid ones which are mostly:

Remember you don't need them in high-res then it's probably something you could afford. If you need 5-10 paid images for non-review blog posts a month I think you can live with that
