I am sure you've noticed that when you search on Google, it will show little pictures next to some of the saearch results. If you are like the majority of people¸ than these little pictures make the links feel more human, and thus they likely to increase the chance that you click on them.
If you write articles, and you'd like to have more people to read them, in just a few steps you could get Google to do this for you.
I think you can even do this on blogs.perl.org, though I would only include the link in the extended part of the post.
