I'm a fan of chunky borders, and I actually kind of liked it like that, however I think it looks about the same with a narrow border, so I changed it. I likely won't keep it up, I'm not much of a GT4 photographer. >_<
Maybe in this context, I'm used to adding that kind of border to a large shot (for my real-life photography. Which I like to think is much better than my GT4 work...I do run the real-life automotive photography contests here at GTPlanet >_<) I don't think it was more than 100px either. To each his own, I suppose.
