Should I have a blog title picture?

Recently I've noticed that a lot of bloggers are busting out the Photoshop to create fancy blog titles to use instead of the typical text only header . As I don't care one way or the other, I'll put it to a vote. I've been using Photoshop-type tools for about 14 years, so I should be able to create something that doesn't suck too bad. So should I create a blog logo or not? Any ideas?
