Install
This is the repository archive. It installs, but the folder name will carry the branch suffix and updates will not flow.
Install straight from GitHub with WP-CLI:
wp plugin install https://github.com/sayhellogmbh/hello-images/archive/refs/heads/master.zipDescription
This is a WordPress plugin that adds an image proxy to resize and crop images inside the wp-content folder.
This is especially useful if you use WordPress as a headless CMS and allow the frontend to use the image sizes it needs itself.
Let's say you have an image:
https://mywpsite.com/wp-content/uploads/2022/02/myimage.jpg
Now you need a cropped and resized JPG you can simply add parameters to your Request:
https://mywpsite.com/wp-content/uploads/hello-images/size-400x400/2022/02/myimage.jpg
hello-images/ is needed for the image manipulation to work, which can be followed by other parameters. Like for example size-400x400/.
How it works
As soon as you activate the plugin a new uploads folder hello-images will be added with a .htaccess file and a PHP Script. The .htaccess routes all not existing images to the index.php script, where the image will be generated.
After the first request, the result will be saved and next time that image is requested it will be returned directly.
Parameters
{width}x{height}=>size-[0-4000]x[0-4000]quality=>quality-[1-100];blur=>blur-[radius: int];
Sizes
The sizes are expected as {width}x{height} parameters. The values can be set from 0-4000. Width, as well as height, can also be set to 0. In this case the aspect ration is retained and the image is only resized, not cropped.
