Positioning the crop area in add_image_size

I cannot count how many times I used add_image_size to register custom image sizes in WordPress, but I never realized that instead of true/false you can also set the crop area by using an array in the fourth parameter.

add_image_size( 'image-size-name', 250, 250, array( 'center', 'center' ) );Code language: PHP (php)

Any of the following keyword combinations:

• left / top
• left / center
• left / bottom
• right / top
• right / center
• right / bottom
• center / top
• center / center
• center / bottom
