Well both. It resizes the shorter axis to your thumb width setting, then crops the longer axis to be the same as the shorter axis. All sites with square thumbs use this algorythm.

Is it a resize, or a crop?

You replace it with the existing function which is in functions.php

# simplex : Perhaps a "keep aspect ratio" or "square" option should be added into the thumbnail options?

Agreed.

Right. But the code is here if they want to use squares :)

I mean, it depends. Some people want square thumb, some want keep original ratio, etc.

It makes for much nicer thumbnails.

How do you think it could help with the core?
