Seeking graphics help

I’m not much of a graphics guy.  I’d like to have some kind of picture to put with each post, but don’t really know where the sources of good pics are (you can tell I’m scraping the bottom of the barrel when I’m putting up pictures of me), and actually don’t have time to do pics in addition to writing the blog content.  I’d be open to anyone who might be willing to suggest pics for me for my posts.  I make $0.00/day writing this blog so there’s no money in it, but if anyone has an interest in graphics and would like the site to look better, I’d welcome some ideas!
