You could just drag the thumbnail to your desktop and then check the size 
of it. They do have a cropping feature I believe its called imgmax  you put 
it at the end of the url feed, not on the image url. You could with 
javascript and or possible php crop the image to a size you'd like that 
matches picasa.  The tag to get the thumbnail is  media:thumbnail and they 
come in 3 predefined sizes in picasa. Can't remember off hand the sizes but 
I remember when setting it up there was an array... so for example... 
 $thumbnail = xpath('media:thumbnail')    
echo '<img src="' . $thumbnail[0] . '">"';

if you change the 0 to a 1 it will give the next larger size.. The largest 
is 2.
