limit_image_size()

Usage

This function runs automatically, so it is not called manually. Is this incorrect?

Demo

Serving images with a max width of 1200px.

`get_post_thumbnail()`

`nebula()->get_thumbnail_src()`

Additional Notes

Original size of this test image is 7360×4545.

This image is loaded via the WYSIWYG editor from the media library.

When this will not control output image sizes:

This function listens for full sizes to be used and limits them. Therefore there are plenty of situations where this will not limit output image sizes.

If the Nebula Option “Limit Image Dimensions” is disabled (which it is by default)
When specified image sizes are added and used
If an image is hard-coded into a template file or stylesheet
Inside galleries
This may not work inside third-party plugins
(Possibly others too)

Here is another test using the WordPress Block Editor.
