For a non-commercial purpose, you are welcome to use them as long as you provide a link to the original photo page on Flickr. As an amateur photographer, I basically love to see my work in unexpected places, and I don't regard it as a "commercial use" just because your personal blog has some advertisements. To make my point clearer, I'm providing some examples that I'm happy or unhappy with:
