Resizing Thumbnails in a SharePoint Image Library

A while back I needed to figure out how to do this for a client project.  Nothing in the MOSS documentation, and searching the Web proved fruitless until I ran across this post from Carsten Keutmann.  Carsten has written a neat little SharePoint utility he calls SharePoint Manager 2007 that lets you get at many of the hidden settings in SharePoint that aren’t exposed in the UI, avoiding STSADM, finding obscure settings in XML files, and the like.
