Optimizations
Plugin configuration 93% from 29 tests
readme.txt Passed 16 tests
Often overlooked, readme.txt is one of the most important files in your plugin
5 plugin tags: backgound-images-lazyload, speed-optimization, lazybg, lazyload, lazyload-bg
lazyload-background-images/lazyload-bg.php 85% from 13 tests
"LazyLoad Background Images" version 1.0.5's primary PHP file adds more information about the plugin and serves as the entry point for WordPress
It is important to fix the following:
- Text Domain: You no longer need to specify the text domain since WordPress 4.6; it must be the same as the plugin slug
- Main file name: It is recommended to name the main PHP file as the plugin slug ("lazyload-background-images.php" instead of "lazyload-bg.php")
