so I have customized the Beuno theme for my wife's blog and for some reason, some of the featured images will not get cropped to 490x200. they are getting squashed instead of cropped. but some of them crop just fine. I can't figure out why some work and some don't. when I look at the uploads folder, it just seems like some of them it doesn't create the cropped images for.
here's her blog: http://theadven-sureof.us
