I have 5 MediaWiki installations which has stopped

Instead of the thumbnails, it displays the message "Incomplete GD
library configuration: missing function imagecreatefrompng".
This may indicate a damaged, missing, or badly configured build of PHP
and/or PHP's GD extension (missing the PNG libraries during build).
At first I thought the problem started because I
imported image
metadata in a XML file and inserted images to the image directories,
from another MediaWiki installation, but this should only affect the
Wiki importing the image metadata, not all of them I suppose. They do
use the same database though.
The way you imported the data shouldn't matter, but the way you imported
the *configuration* might. It's possible that your current server
doesn't have PHP's GD extension set up at all, but that the one you
copied your wiki from did.
Check your LocalSettings.php; try setting $wgUseImageResize to 'false'
instead of 'true'. This will disable the use of server-size resizing, so
large images will be scaled down by the browser.
Alternatively, check if the PHP GD extension is enabled, and
install/enable it if if necessary. (It may be present as a .dll file but
not enabled in php.ini.)
If it has any significans I am using a Windows 2003
server with IIS
6.0
