[Contribution] Solution (temporary) to crop specific image sizes

I want to share a tip to crop ONLY specific image sizes. I’m share here because this solutions is not the “better solution”, but works. Let’s to code:

In my theme functions.php file:

function sc50k_check_size_to_crop($size){
	$allowed_sizes = array('thumbnail', 'woocommerce_thumbnail', 'woocommerce_single', 'woocommerce_gallery_thumbnail', 'shop_catalog', 'shop_single', 'shop_thumbnail');
	if ( !in_array($size, $allowed_sizes) ){
		return false;
	} else {
		return true;
	}
}

The code above verify if the $size in the crop moment is an $allowed_size. In the code, I’m using the Woocommerce sizes. I just want to crop product image sizes. And ONLY the thumbnails.

In the plugin file plugins/square-thumbnails/admin/class-square-thumbnails-admin.php, search for the foreach($meta['sizes'] as $size=>$m){. This foreach must to be:

foreach($meta['sizes'] as $size=>$m){
        $kontinue = sc50k_check_size_to_crop($size);
        if ($kontinue) {
          //$m['file']=$path->dir.$m['file'];
          $result=$this->create_square($m);                    
          $meta[$size]['width']=$result->sqW;
          $meta[$size]['height']=$result->sqH;
        }
    }

This is a little change in the plugin file. It verifies if the current size (crop moment) is allowed. If returns true, continue with the square crop. If false, skip.

IMPORTANT: In the first plugin update, this change will be removed. That’s the reason to be a temporary solution. For each plugin update, this foreach code must be adjusted with the code above.

Sorry my bad english, I’m brazilian. If anything is wrong, forgive me.
