Theme gallery images missing from user > settings

[caseyrlentz]

Looks like the theme gallery images inside of the user account page are broken.

You need to generate the previews firstly ;)

$CmdLine = '/usr/bin/phantomjs "' . dirname(FILE) . '/render_build_preview.js" "' . SERVER_ROOT . '" "' . STATIC_SERVER . '" "' . $Style['Name'] . '" "' . dirname(FILE) . '"';
$BuildResult = json_decode(shell_exec(escapeshellcmd($CmdLine)), true);

/*

• This page creates previews of all supported stylesheets
• SERVER_ROOT . '/' . STATIC_SERVER . 'stylespreview' must exist and be writable
• Dependencies are PhantomJS (http://phantomjs.org/) and
• ImageMagick (http://www.imagemagick.org/script/index.php)
