While the settings screen now performs better in that it reliably allows me to enable ghostscript after setting the path which it didn’t before. It still doesn’t generate thumbnails as it should. * The reason for this is that the call to getThumbnail() calls self::getThumbers(). getThumbers() checks whether ghostscript is now active (which it is because I set it in the settings screen) then calls getGhostscriptExecutable() which is still calling exec(‘which gs’) to find the executable which we know fails. * I also had a problem in that after finding that the new version didn’t work I patched it as above but the document_gallery options already contained a lot of [‘thumber’][‘thumb’][ID] = false settings. The only way I could clear these was to uninstall, re-install, patch then enable the plug-in again. Not often needed perhaps, but how about adding a ‘regenerate thumbnails’ button to the settings screen which will clear out all of these settings forcing the plugin to regen. This could also help if a user upgrades ghostscript or chooses to change options etc. * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[Document Gallery] Thumbnail generation fails after upgrade to 2.n](https://wordpress.org/support/topic/thumbnail-generation-fails-after-upgrade-to-2n/) * Thread Starter [fredd500](https://wordpress.org/support/users/fredd500/) * (@fredd500) * [12 years, 1 month ago](https://wordpress.org/support/topic/thumbnail-generation-fails-after-upgrade-to-2n/#post-4788079) * Here’s a proposed patch that uses the user defined path to gs if it exists.

On re-installing the plugin, it failed to detect Ghostscript. I can run it from the command line, but I think that is irrelevant. I’m using TSOHost in the UK and I SSH to a different IP address to where my web server sits. I think the path on the web server might not be set correctly. * I defined the path to Ghostscript manually by setting it to the standard gs path on linux (and the same as it is on the box I ssh to) /usr/bin/gs. * The getGhostscriptThumb function uses $options[‘gs’] to identify the binary to call. Since I have set this, it works. * The problem lies in the fact that getGhostscriptExecutable() fails because it doesn’t appear to reference my setting at all and insists on calling exec(‘which gs’). This in turn results in getThumbers() not adding the getGhostscriptThumbnail() function to $thumbers and so it is never called. I think the ‘which’ command fails – probably because the path isn’t set or something like that. * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[Document Gallery] Thumbnail generation fails after upgrade to 2.n](https://wordpress.org/support/topic/thumbnail-generation-fails-after-upgrade-to-2n/) * Thread Starter [fredd500](https://wordpress.org/support/users/fredd500/) * (@fredd500) * [12 years, 1 month ago](https://wordpress.org/support/topic/thumbnail-generation-fails-after-upgrade-to-2n/#post-4788075) * OK. I’m very confused too. I’m using this code: * `echo "

";` * in a template page. It works! The image is displayed and what’s more odd is that the image is the first page of the PDF, not the last as I reported earlier! * Interestingly (or maybe not) when I run the test code, I end up with .png’s in my uploads directory. When I upload attachments through the media interface, I end up with .jpg’s in my uploads directory. * I’ve just uninstalled the plug in and re-installed it from a new download so definitely have 2.0.5. * I see in the code that it checks to see if a thumbnail has already been generated. How does it do that? Where does the existing thumbnail come from? I’m wondering whether I could remove all the existing thumbnails from the database effectively forcing them to be regenerated. * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[Document Gallery] Thumbnail generation fails after upgrade to 2.n](https://wordpress.org/support/topic/thumbnail-generation-fails-after-upgrade-to-2n/) * Thread Starter [fredd500](https://wordpress.org/support/users/fredd500/) * (@fredd500) * [12 years, 1 month ago](https://wordpress.org/support/topic/thumbnail-generation-fails-after-upgrade-to-2n/#post-4788017) * I’m making some progress. I haven’t done your last step, but can confirm that exec() is available and get_tmp_file() returns the path to the root of my uploads/ directory. * Checking in there, I can see some temporary jpgs. Woohoo. Browsing to them [http://site/wp-content/uploads/md5hashstring.jpg](http://site/wp-content/uploads/md5hashstring.jpg) displays a JPG version of the last page* of my PDF. Double WooHoo. * So, the issue I guess is either the script is timing out before it completes the move of the temporary file to it’s final resting place, or, for whatever reason, the temporary JPG is created, but it’s path not passed to the function which then moves it. * * I recall Ghostscript generating a JPG of the last page before.
