You must install Image::Magick (perlmagick) and/or GD on your server to use this feature.  Contact your server administrator / hosting company and ask them to install these Perl modules.  Or, if you have root access to your server, you can install them yourself by running these commands:

# perl -MCPAN -e 'install Image::Magick'

# perl -MCPAN -e 'install GD'

Alternatively, you can just disable the thumbnail features $PREF{enable_image_thumbnails_in_filelist} and $PREF{enable_folder_thumbnails_in_filelist} in FileChucker's PREFs Section 11.
