The plugin provides the functionality to adjust the crop region of cropped images. It add buttons to the edit-pages and media-dialog to access a crop-editor.
In the crop-editor you can choose one or more (if they have the same ratio) imagesizes and cut-off the part of the image you want.

The plugin is especially useful for theme developers who want to keep full control over cropped image sizes. If you want to dive even deeper, you can get informations about the hooks and filters on the github page of the plugin.

How to define cropped image sizes?

The plugin do not add additional image sizes, it only provides functionality to edit the crop area.

You can use “add_image_size” inside your functions.php to add additional cropped image sizes. See “add_image_size” documentation.

After you add the image-size any futher image uploads will produce a cropped image “my-custom-image-size” which you can use in post-loop:

What internal rules the plugin use for cropping?

The plugin will only crop image-sizes where crop is set to “true” (hard crop mode – see: https://codex.wordpress.org/Function_Reference/add_image_size).
If you had set one image dimension in add_image_size() to “0“, the plugin will crop it in the ratio of the original image.
If you had set one image dimension in add_image_size() to “9999“, the plugin will change the 9999 to the actual size of the current original image.
You are able to crop all images with the same ratio at once (default) or and any imagesize (and ratio) seperate.

How to use this plugin on ACF taxonomy-images

The “Adavanced Custom Fields” plugin has a functionality to add images to taxonomies. To add cropping functionality on these images you have to add a small code-snippet to your functions.php
Have a look on the github readme-page for details.

I’ve cropped the image, but the new version do not appear in the frontend.

If you had viewed your image on the site before, your browser has cached the image. You can hard refresh the page by hitting:
* “CTRL + F5” (on Windows)
* “Apple + R” or “command + R” (on Mac/Apple)

Is it possible to crop an non-cropped image-size?

No. The purpose of this plugin is to provide control for the wordpress automatic crop. If you want to crop let’s say the full-size image you should

a) upload it in a better format in the first place
OR b) use the Standard WordPress-Image editor to crop the image.

Where can I get developer information?

A documentation with a list of all actions and filters can be found on the Github page of the project.

I have two image-sizes that have nearly the same ratio. I want to make use of the feature “Crop all images with same ratio at once”, but cause the ratios are slightly different they wont be selected together.

You can add the following filter in the functions.php of your theme to adjust the ratio of one or more specified image-sizes.
CAUTION: use only when the ratios are really close.

I display the cropped image in the backend in an custom meta-box. It does not update after the modal-dialog closed. Is there a way to fix this

Yeah, there is a way. After the crop-thumbnails-modal closed it triggeres a javascript event on the body element. You could use jQuery to cache-break your cropped thumbnail (in backend-view).
The event called “cropThumbnailModalClosed”. The plugin also provides a global function that could be called (only in post-edit-view and mediathek) to do the cache-break.
Example-Code:

What languages are supported?

You may have a look on the Translation Page.

I want to contribute code.

Fantastic, i published the code on github. But be warned, i am carefully evaluate new features.

If you fork and planning to publish the forked plugin, please contact me.
