Wbcom Designs – Activity Link Preview For BuddyPress

Not a fan of all their plugins but this one does the job perfectly (now that the fixes I suggested have been implemented). Highly recommended.

Works as it says


Thank you for making this and putting it out for free. It isn't easy to find link preview features sometimes. 



Even if it has to be a pro/paid version, you might think about finding a way to have the link preview's image uploaded to wp-content uploads and then served from there. I'm sure that's not super easy to do, but in order for this to work consistently and work well on larger sites, the images need to get cached or hosted within the same WordPress installation.


Simple and effective

This plugin will allow you to automatically show previews of external websites when a user hovers over a link in your posts. 
It’s designed to work “out-of-the-box” and no changes should be needed on your part to make it work. 
However, if you are familiar with CSS, you can apply “link previews” to links in other places in WordPress site by specifying any CSS selector that you want.
A free or paid <a href="https://www.webshrinker.com" rel="nofollow ugc">Web Shrinker</a> account is required as you will need a service API key.
