in reply to how to make them square... no, dont use photoshop, it will take for ever.
look at
http://www.cerdmann.com/thumb/ they have an example, about forcing it to crop on the sides.

second, i have a problem, i am trying to replace the normal product_thumbnail.tpl so that all the pictures will go 'into' the mod, but i get an error here..
{thumb file=$tmbn_url longside="100" link="true"}
Fatal error: Smarty error: thumb: parameter 'file' cannot be empty and must exist in /hsphere/local/home/samor/edecodrive.com/Smarty-2.6.12/Smarty.class.php on line 1095
Can anyone help? i already tryed, double quotes, single quotes, etc... i even tryed entering the name of file, directly... but it still says that error..
