BuddyPress magazine theme thumbnails and post images

I have added my images to the library and attached them to my posts. They work fine in the slideshow on the front page and look as they are supposed to.. however on the thumbnail view and on the actual posts (after clicking 'read more') they cut off the top of the images.

How can I get them so that they align from the top instead of cutting the top off?

Attached is an example so you can see what I mean.. I currently only have an image on my 'news post 2':

Any help much appreciated. Cheers
