We hava a thumbnail making routine on our Plesk6 server. The same routine works on our Windows server and on our Cobalt RAQ, so the routine is not at fault.

The routine uses Image::Magick and fails to create the new thumbnail file . The error log reports that delegates for decoding the image format cannot be found. We've tried multiple image formats with the same results.

This is a Plesk6 that was upgraded from a Plesk5 by EV1net prior to leasing it to us. I assume that the upgrade changed the original paths to JPEG, PNG, TIFF etc. and autoloader can no longer find them.

Does anyone know the path to the image delegates on Plesk6 and where I should edit in these new paths?

We found the solution to this problem. This server was leased to someone else before ev1 leased it to us and the installation of image magick had been botched. Ev1 did not cleanup the server before re-leasing it. Uninstalling and re-installing image magick corrected the problem.
