WordPress Media Uploader缩略图选项

Question

in WordPress you can create Media Library popup by calling wp.media() function, this works fine but the problem is that there's no option to choose image size(thumbnails) of selected image. Is there a way to add support for thumbnail selection ? I'm using WordPress 4.5.2, code sample:

wp.media.frames.selectFile=wp.media(
{
    multiple        :   false
});

Thanks for help !

Yes, there is function in WordPress wp_generate_attachment_metadata()

Example: <?php wp_generate_attachment_metadata( $attachment_id, $file ); ?> <?php wp_generate_attachment_metadata( $attachment_id, $file ); ?>
