Hi again,

Shane from ewww suggested using ‘mpp_generate_metadata’ for the second hook and problem is solved!

Another thing I noticed is mpp_handle_upload looks like a filter hook, not an action hook. (See line 267: https://github.com/buddydev/mediapress/blob/master/core/storage/class-mpp-local-storage.php). I tried changing ‘add_action’ to ‘add_filter’ for the first hook, result seems the same. I guess as long as ewww_image_optimizer_handle_upload is returning what the hook expects it will be fine either way. But maybe good practice to use ‘add_filter’ here?

Here is the code I am testing now:

—
add_action( ‘init’, ‘mpp_ewww_optimizer_bridge’ );
function mpp_ewww_optimizer_bridge() {

if( function_exists( ‘ewww_image_optimizer_handle_upload’ ) ) {

add_filter( ‘mpp_handle_upload’, ‘ewww_image_optimizer_handle_upload’ );
add_filter( ‘mpp_generate_metadata’, ‘ewww_image_optimizer_resize_from_meta_data’, 15, 2 );

}
}

Just tested with a 5120×3400 image upload and it successfully processed the original, resizing down to 1920px as specified in ewww settings, and compressed by 96%! So all seems to be working.
