I had issues with my theme and the plugin didn't work - contacted the dev team and they fixed it within few days - I was, of course, happy to purchase PRO version of the plugin.
The team is highly professional, polite and friendly - it was a real pleasure to work with them! All the best in your future projects guys!
Easy installation and works like a dream. I didn't like that image url's open in new window but looks like that feature is available on their pro version. I may purchase because I think opening in same window is important.
UPDATE: I purchased the pro. After installation I noticed that the featured images were not working on my category pages, something to do with my design. The creators had emailed me directly to thank me for my purchase and I replied with the problem. They offered to fix so allowed them to log into my Wordpress back end and within hours they sent me a tweaked version of the plugin. All works great now site wide.
The pro version is worth it.
Exactly what I need.
If you have Simple Lightbox installed and paste the featured image 'File URL' in the box this plugin adds, when you click on the featured image it opens the original size image in the lightbox!
Woohoo!!! Finally featured image can be enlarged without having to write your own code.
