Something you need to watch out for when you upgrade an old site to the new version of Bootstrap is that one of the classes in Images has changed a little bit in the new version. So, you may have noticed that these pictures don't look like polaroids, which is what they're supposed to look like. Now if we take a look at the manual, you'll see that in the old Bootstrap, the class for creating this effect right here was called img-polaroid. In the new version of Bootstrap, this is now called img-thumbnail. So if you've got any Polaroids that you're using, you need to make sure that you watch out for that class change.
