Hello Adam,
I just downloaded the latest code und in your zip file and when I go to
...\SelectImage.aspx I see the following code:
<li>[[AutomaticImageResizeOnOff]]
<%= secset.AutoResizeUploadedImages? "on":"off" %></li>
The file SelectImage.aspx in your zip file was last changed on 30th April 2007.
