<p>This plugin was created to make easier the life of people that want to get pictures, images, photos from the web, rather than download your image on your computer and, then, upload it in your media library, you can paste the image url in the field and get it from the web straight in your media library. Afterword you can click to set the post thumbnail and you will find the aquired image in your media library, ready to be inserted in your post.</p>
<p>This plugin is a simple box, activate the plugin, follow the settings link, activate the option to see the new form in the post thumbnail metabox in the post edit page and it’s done!</p>
<p>I created this plugin mainly for me, when I was creating websites I incurred the need to quickly grab some of my photos from another website ands that was the reason of this idea, it is something like creating a tunnel from one site to another to transfer images.</p>

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.
