This is no April Fool’s joke.
I have been trying, without success, to get the ImageMagick Perl module to compile and install on the server ever since we rebuilt the system on December 21. This module is required for the automatic generation of thumbnails via the Upload File dialog box, accessed via the left sidebar link in the admin interface.
However, Movable Type also provides hooks for another back-end image generator called NetPBM. I had also tried a few times to install and configure this module. Tonight I finally met with success.
The linked image of the PUBS logo in this entry is an example of a pop-up window with an auto-generated thumbnail.
