I see a lot of blogs (coding horror for example) that seem to feature random pictures in the entries.
Would I be correct in saying they probably didn't seek permission to use those images? What are the rules around this? Can I use any image I want in my blog post? Or do I have to seek permission?
I'm thinking there might be a sort of reasonable journalistic usage thing here if your blog is somehow classed as a journalistic venture? Or am I mistaken?
