Like knitncook, I like pictures of FO, WIP and details about the yarn, needles, lessons learned etc. I don't mind a little off-topic stuff, like, I'd love to see a few pictures of your salt and pepper collection.
And it looks like you're off to a good start.. I enjoyed it and you've already got several comments so that's encouraging!
But overall, I find my favorite blogs have great pictures and, there's something about them that I find inspiring... they make me strive to be a better knitter.
