PDF Thumbnail Generator


I've used this on multiple sites and have found it invaluable.



While I've struggled with getting the required ImageMagick set up and working on a few servers – each one requiring a slightly different approach owing to different OS and security settings – this is not the fault of the plugin or plugin author.



I'm not sure what one reviewer means by this being built-in to WordPress; to the best of my knowledge that is incorrect.


Invaluable for building document libraries and the like
