Image Placeholders not working

[tibor]

Bug Description

I tried to use the Image Placeholders plugin for my website with custom theme, but it wouldn’t change anything in the frontend. Do I need to add anything to my code as well?

Additional Context

• PHP Version: 8.1
• OS: macOS
• Browser: Chrome
• Plugin Version: 1.1.0
• Device: MacBook Air

According to the readme:

This plugin determines and stores the dominant color for newly uploaded images in the media library within WordPress and then uses it to create a placeholder background of that color in the frontend, visible until the image is loaded.

So it only works for newly-uploaded images. Did you try uploading a new image to see if the placeholder background color is present?

Ideally preexisting images already uploaded to the media library would have their dominant color computed, such as via a WP Cron process. This is not implemented, however.

Regenerating images using wp-cli or a plugin should get the code to generate the placeholder images.
