Generating thumbnails for pdf files with ghostscript ==================================================== Ghostscript (gs) is a PostScript and PDF language interpreter and previewer. Sulu is able to use the **gs** commandline program to generate thumbnail/preview images for pdf files. The location of the **gs** program depends on your system and needs to be configurated for Sulu to find it. Add configuration `config/packages/sulu_media.yml`: .. code-block:: yaml sulu_media: ghost_script: path: /usr/bin/gs Common locations are: * /usr/bin/gs * /usr/local/bin/gs You can also try to use the ``which gs`` command to get the location.
