What amount of support is needed?

Adding upload support for additional file formats can be done by adding the following code to your themes function file.

// add extra file support for media uploader support
function feeral_mime_types($mimes) {
$mimes['svg'] = 'image/svg+xml';
return $mimes;
}
add_filter('upload_mimes', 'feeral_mime_types');
