Why aren’t my images lazy loading?
Lazysizes filters images added to the page using
get_avatar. If your images are added using another function (
wp_get_attachment_image for example), lazysizes does not filter them. However, you can filter the HTML yourself by passing it to
For example, if a theme has:
Changing it to the following would lazy load the image:
echo get_lazysizes_html( wp_get_attachment_image($id) );
But this plugin looks like Lazy Load XT!!
Yes, it does. The PHP code for this plugin is heavily based on that of Lazy Load XT.
The main difference is that this plugin is a bit simplified, and is using a completely different lazy loading library, with no jQuery dependency.
Thanks to dbhynds for making the Lazy Load XT plugin. Without that project, this one would not be possible.
Why is this plugin called the same as the lazysizes JS library?
There are a couple of reasons:
- I like the name. It’s good.
- I’m hoping it will help people discovering the plugin. I originally tried searching for a WordPress plugin using the library myself, and other people might be trying the same.
If you are wondering, this plugin is not affiliated with the lazysizes project. I got permission by aFarkas to use the name, but that’s as far as any connection between the two go.
- Add support for the aspectratio plugin for lazysizes, which makes images have the right height while loading. Thanks to Teemu Suoranta (@teemusuoranta) for implementing.
- Update the lazysizes library to version 4.1.5
- Fix lazy loading of elements without a class attribute, like some iframes
- Fix translation loading
- Remove unused code for advanced settings
- Fix text domain loading
- Updated readme
- Initial version of the plugin
