Generates thumbnail for PDF file automatically after file is uploaded to the Media library.
You can also generate thumbnails for old PDF files that are already in the Media library – you can generate missing thumbnails or regenerate all thumbnails.
Imagick library must be installed on your server, otherwise this plugin will not work
Does what it says on the tin! Generates a thumbnail which can be used however you need to.
Great for building a library of pdfs – wrap the shortcode in a link and BANG, you’re done!
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.
In certain situations, this can be a very handy plugin. It works as advertised. It is simple to use, and allows developers many options of how to implement it and customize it when needed.
Using custom fields for file uploads, I’ve built this into template files, so my customers can simply upload their PDF files and have them presented nicely with no further effort required.
In the right situation, it can save many tedious and repetitive steps. It allows my clients to easily and automatically present their PDF files in an attractive way without having to fire up Photoshop or some other image creation method each time. No more need to upload a PDF file and a separate image file. This plugin takes care of it all in one easy step.
p.s. – the developer seems to be excellent at responding to questions in the plugin’s forum page too!
This plugin does not work with ImageMagick’s current default settings. In order to make it work you have to change IM’s settings and thus open a possible security hole (cf. “ImageMagick security policy ‘PDF’ blocking conversion” on StackOverflow).
But if you do so, you don’t need that plugin at all, because WordPress then does the thumbnail generation out of the box, and those image files only have 10 percent the size of those generated by this plugin.
This plugin exceeded my expectations by allowing me to dynamically preview a PDF file without any links to it or similar.
One of the standout features of this plugin is its high level of extensibility. With numerous hooks provided, it is easy to customize and tailor the plugin to meet specific needs and requirements.
