Screenshot Generator takes screenshots of posts and pages when they are updated. These screenshots can be used for e.g. previews in social media.
Screenshot Generator is a WordPress plugin that takes screenshots of posts for social media etc. when they are updated. It uses PhantomJS to do this.
Why? When developing Toptrust, I was tired of manually adding images of posts when sharing on social media. This was especially true for pages that had no featured/thumbnail images. I wanted screenshots to be taken automatically, and so Screenshot Generator was born.
When you update a post or page, a screenshot is automatically taken in the background.
After a few seconds, the screenshot URL is saved to the post's meta key _scrgen_screenshot
.
An og:image
and twitter:image:src
is automatically added to the meta tags
when viewing the post. These are only added if the post doesn't have a
thumbnail, in which case the plugin expects the thumbnail to be added by
you or another plugin. You can change this in the plugin settings page.
If you want to retrieve the screenshot manually, you can do so inside a post:
<img src="<?php echo scrgen_screenshot(); ?>" />
