Advanced Popups


I tried: Elegance Modal Box, WP Modal, Popup Maker and many many more. ALL of them have issues showing a simple image in full screen. 



This is the ONLY plugin which has no bloat, and is able to easily show images as full screen. 



Also a HUGE plus for not taking over the Admin Menu, it sits perfectly in setting > popup. Instead of ALL the other plugins pushing their plugin into the main menu options.



As a fellow dev, I would pay for this versions.


Tried 10 other plugins, this one is BEST!

Display high-converting newsletter popups, a cookie notice, or a notification with the light-weight yet feature-rich plugin.
