Removing frames from individual photos

Hi guys, I was wondering if there was a way I can remove frames from some individual photos in posts. I like frames being used for most of my photos, but some I don't want them for and want to remove them. For example, on the following page http://www.howtomovetogermany.com/departure-and-bangkok/ you will see I have reviews and I give them an amount of lebkuchens (German cookies) out of ten. I post a image to show this but it looks weird with the frame. Thanks for your help Paul
