The best way IMO is to use CCK and imagefield/imagecache. Then you have 
an "image" field and can call a different imagecache preset in your 
node-content_whatever.tpl.php file when $teaser is true/false. This is 
what I have used in the past for this functionality and works quite well.

If you need to use img_assist (using inline images), you could do this 
in hook_nodeapi() as Steven says and shrink down any images, but this 
method is a bit clunkier.
