在 WordPress 中上传特色图片时如何添加自定义宽度验证？

Question

Is there a way to check image width/height when it is uploaded as featured image in WP post?

For example, I click 'set featured image', then Media tab opens, I go to 'Upload files' and try to upload a huge image and there is an error like 'The image is too big'.

Check this code

add_image_size( 'amolood-featured-image', 90, 590, true );

width : 90
height : 590
