Here is modified code if you do not want to worry about the order of the photos being sideloaded needing to match the order in which they appear in the content and also matching the sizes.
`

$media = get_attached_media( 'image', $id );
$img_array = [];
$dir = wp_upload_dir();
foreach($media as $media_id => $item) {

$directory = explode('/', $metadata['file']);
$metadata['directory'] = "{$directory[0]}/{$directory[1]}";
foreach ($metadata['sizes'] as $size => $args) {
$img_array[$args['file']] = array('id' => $media_id, 'url' => "{$dir['baseurl']}/{$metadata['directory']}/{$args['file']}");
}

Hey @gitdavidhunter, sorry for not responding sooner!
Remove the "src" attribute, or remove the entire![]()
tag? Just wanting to confirm that (unless you're wanting to have dead ![]()
tags floating in the content).
