With your method it would be very tricky, if it’s possible at all. What you could do is use a custom header with flexible dimensions. That would allow the user to upload the header image and then crop it how ever they needed easily. // Register Theme Features function custom_theme_features() { // Add theme support … Read more
I was confusing add_image_size with set_post_thumbnail_size. The problem with the latter is that you can only set one ‘thumbnail’ size. I wanted to be able to keep the original image intact and apply a custom crop to the thumbnail version of the image. I’m using multiple image sizes around the site as the ‘thumbnail’ though. … Read more
Try this code $crop = array( ‘center’, ‘center’ ); $resize_img->resize( $wpc_image_width, $wpc_image_height, $crop);
No, there’s not a way to do this by using the_post_thumbnail(), neither it’s recommended. What you are looking for is cropping the images on the fly. This will cost heavy server resources, especially when you have a lot of images to work with. But in theory, to do so, you can make a script that … Read more

what you are describing here (cropped big size image in Edit Media screen) is a perfectly normal behavior when you use Apply changes to: All image sizes while cropping image and I believe the same thing could happen during upload when $crop param is set to true for all registered image sizes (similar to how … Read more
I think you are good, but you don’t need to use other functions. You have all in File: wp-includes/media.php For instance, you may _wp_get_image_size_from_meta to get the image dimensions, so you don’t need to use something like this: $size = getimagesize($file); $width = $size[0]; $height = $size[1]; $mime = $size[‘mime’]; To get the image dimensions … Read more
