Thumbnail blocks of Blogs, Groups, etc crop images

Hi. I'm using 7.2.1. I'm wondering why images I upload to Blogs, Groups, etc all get cropped to the size of the square thumbnail.

Wouldn't it make more sense to keep the aspect ratio and size it in the thumbnail box ie. fit the image into the square of the thumbnail box?

If I can change this setting to get Dolphin to do this, please advise.

If I can't setup Dolphin to fit the image into the box, could this be put in as a feature request?

For the images in Photos module (Groups, Store, Events modules uses Photos module):

Images are cut-off during resizing you can change this behaviour by changing the the following lines in modules/boonex/photos/classes/BxPhotosConfig.php file:

...
'browse' => array('postfix' => '_t.jpg', 'size_def' => 240, 'square' => false),
'browse2x' => array('postfix' => '_t_2x.jpg', 'size_def' => 480, 'square' => false),
...

Blogs images aren't square but it maybe they are fit into square box using css.

Thanks again Alex. Works a treat.
