Remove the original image from the server after Wordpress generates the thumbnails
I need to remove the original image that gives rise to Wordpress thumbnails after the thumbnails are generated. I have 3 sizes of thumbs that I use, but to prevent the server from getting unnecessary files I need to remove the original, which usually comes with more than 4000px in size and with more than 2.5 MB in size. I searched for some content related to this issue but found nothing. Is it possible to remove the original after thumbnails have been generated? And if so how can I find the answer?

You can do this using the following code:
(source: How to automatically use resized images instead of originals)
add_filter( 'wp_generate_attachment_metadata', 'replace_uploaded_image' );
function replace_uploaded_image($image_data)
{
// abortar se não houver versão "large" da imagem
if ( !isset($image_data['sizes']['large']) )
return $image_data;
// paths do upload e da imagem grande
$upload_dir = wp_upload_dir();
$uploaded_image_location = $upload_dir['basedir'] . '/' . $image_data['file'];
$large_image_location = $upload_dir['path'] . '/' . $image_data['sizes']['large']['file'];
// deletar original
unlink($uploaded_image_location);
// renomear a imagem "large"
rename($large_image_location, $uploaded_image_location);
// atualizar o metadata da imagem e retornar
$image_data['width'] = $image_data['sizes']['large']['width'];
$image_data['height'] = $image_data['sizes']['large']['height'];
unset($image_data['sizes']['large']);
return $image_data;
}
You can also change the version large to a custom one, as seen in Auto-modifying original [full size] images :
add_image_size( 'new-large', 1600, 1200 );
And then, just swap all occurrences of $image_data['sizes']['large'] for $image_data['sizes']['new-large'].
Look... I believe only manually. You can find them either in FTP, in the folder: wp-content/uploads / or in the media library.
However, I see no need to remove the images. The vast majority of hosts usually have more than 5GB of space, which is quite difficult to "fill". :)
