Image generators are fun, too. I looked on ImageChef (http://www.imagechef.com/ic/make.jsp?tid=Texas+License+Plate) and saw that I could customize a license plate. I recently considered doing this for real – I have always wanted a customized plate with the Texas horned lizard on it. After checking, I decided it was too expensive, so this will have to do.
Again, I used the feature in WordPress.com that allowed me to put alternate text where the caption would go.
I have learned how to create some of these effects in Photoshop. However, for a quick preview of an effect, the image generators might work just as well.
