[wp-hackers] Thumbnail creation question

[Bill Erickson]

There's a great code snippet on this trac ticket (
http://core.trac.wordpress.org/ticket/15311 ) that allows dynamic image
resizing. You specify the dimensions and if it should be cropped, and the
function checks to see if that image size exists, and makes it if it
doesn't.

I'm using it on a site right now that would have had about 15 custom image
sizes throughout their site, but only one or two would have been used per
image uploaded.
