How to rewrite and set headers at the same time in Apache

Question

I have a catalog of images that are alternately viewed directly in the browser and downloaded at another time.

So let's say I have the file / gallery / gal _4254.jpg.

I want to make / download / gal _4254.jpg start loading the image, and not view it. / Download is empty, all images are in / gallery.

I can match download directory requests with other files successfully

<Directory /var/www/download>
    RewriteEngine on
    RewriteRule (.*)$ /gallery/$1
</Directory>

and I can already force upload files to the gallery gallery by setting

<Directory /var/www/gallery/>
    ForceType "image/jpg"
    Header set Content-Disposition "attachment"
</Directory>

therefore setting the headers is not a problem. I don’t want the gallery to have headers at all, it just asks for / gallery / * through / download /, which are being overwritten.

#does not work - just views the image like when it is viewed directly
<Directory /var/www/download>
    ForceType "image/jpg"
    Header set Content-Disposition "attachment"
    RewriteEngine on
    RewriteRule (.*)$ /gallery/$1
</Directory>

</Directory>

Answer 2

. :

<Directory /var/www/download>
    RewriteEngine on
    RewriteRule (.*)$ download.php?getfile=$1
</Directory>

download.php - (NOT TESTED):

<?php

if ($_GET['getfile']){
  $file = '/var/www/gallery/' . $_GET['getfile'];
}

$save_as_name = basename($file);   
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: no-cache');
header("Content-Type: application/octet-stream");
header("Content-Disposition: disposition-type=attachment; filename=\"$save_as_name\"");

readfile($file);
?>
