The lightbox feature is perfect for portfolio posts, but is there a way to selectively turn off that function on a post header image? On my regular blog posts, the header images don't need to get any bigger than 568x240, so having a lightbox doesn't make sense for those particular posts. People get a rollover telling them they can magnifying the image, but since I don't have a bigger image, they get a lightbox popup with the same image as the post at the same size.
Is this possible to do this?
