## FAQ
### How to use?
Just activate the plugin. Additional settings is not required.
### What is lazy loadind?
Lazy loading is the strategy of loading resources as they are needed, rather than
in advance. This approach frees up resources during the initial page load and avoids
loading assets that are never used.
Images that are offscreen during the initial
pageload are ideal candidates for this technique.
### How To minimize content jumping or unpredictable behavior images before loading?
Add width and height attributes to image.
```
```
### How to lazyload a background image?
In case you want to lazyload a background image via a class you can do so by using
the addClasses option:
```
```

### [403 in every png upload](https://wordpress.org/support/topic/403-in-every-png-upload/)
[nickdesignz](https://profiles.wordpress.org/nickdesignz/) Hwevrer 17, 2022
This tool generates also a code which adds a src to your png, this source is a 403;
src="//www.w3.org/2000/svg%22%20viewBox=%220%200%201228%20294%22%3E%3C/svg%3E" class
="attachment-full size-full lazyload" Source is invalid which causes many 403 errors
on your site. ALSO: It’s not necessary to link to another source on a third plattform.
This is just slowing down your site. Don’t install!
### [Great Plugin for saving time](https://wordpress.org/support/topic/great-plugin-for-saving-time/)

This plug-in will transform all your actual PNG media to WebP + automatically transform
them in WebP when downloading new loud formats, in a beautiful manner. Simple in
the presentation but powerful in the application. I recommend it a lot !

### [Best plugin for lazy images!](https://wordpress.org/support/topic/best-plugin-for-lazy-images/)
[kazmetika](https://profiles.wordpress.org/kazmetika/) Est 27, 2020
Works with ajax pagination. Reserve space for images and when the image appears
content doesn’t move.
