Overview

This WordPress plugin optimizes page load times by implementing lazy loading for images, ensuring that they are only loaded when they come into the user's viewport. It utilizes jQuery.sonar, a script by Dave Artz from AOL, to achieve this functionality. The plugin is a collaborative effort drawing on code from the WordPress.com VIP team at Automattic, the TechCrunch 2011 Redesign team, and Jake Goldman from 10up LLC, thereby combining expertise from several leading tech entities for optimal performance.

User sentiment analysis

Users appreciate this WordPress plugin for its simplicity, ease of use, and effectiveness in improving website load times, especially on image-heavy sites. Many users report noticeable improvements in their website's speed and performance after installation, without needing any configuration. The plugin is lightweight and helps in reducing bandwidth usage, which is advantageous for posts with numerous photos. However, there are significant drawbacks. Some users report malware infections and issues with certain themes and sliders, causing images not to load properly. The absence of configuration options and support is another common complaint, leading to difficulties in troubleshooting and fine-tuning the plugin for specific needs.

Having this plugin installed on my WordPress pages for some time resulted in having them all malware-infected which happened literally yesterday. The plugin had its name changed to some ‘WordPress CMS module’ and its directory name was changed as well.

It produces random grayed out pictures within Jupiter theme image galleries. The galleries work like charm after disabling this bundled plugin.

I hate plugins that don’t have any sort of settings or anything. I can’t tell if it’s actually doing anything. How can I check?

Seems to work for some images but not for all, with no real explanation about why. There are no configuration options so I couldn’t find a way to fine-tune it.
