I believe you can add a filter to upload_mimes to restrict to certain types. The upload_mimes hook:
1 2 3 4 5 6 7 8 9 10 | add_filter('upload_mimes','restict_mime'); function restict_mime($mimes) { $mimes = array( 'jpg|jpeg|jpe' => 'image/jpeg', 'gif' => 'image/gif', 'png' => 'image/png', ); return $mimes; } |
