serve static png file with apache2 with a fallback if not available

i want to serve static (*.png) files with apache2 from /var/www/html/tiles/. if a png file is not available, it returns a 404 (correctly). what do i have to do to make it redirect to a fallback.png if the requested file is not present?

i am currently using the default apache config with this default site:

<VirtualHost *:80>
    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
    #FallbackResource /fallback.png

    <Directory /var/www/html>
        Options +FollowSymLinks
        AllowOverride All
    </Directory>
</VirtualHost>

what i tried to add is:

<VirtualHost *:80>
    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
    #FallbackResource /fallback.png

    <Directory /var/www/html>
        Options +FollowSymLinks
        AllowOverride All
    </Directory>

    RewriteEngine On
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule \.(png)$ /tiles/fallback.png [L]
</VirtualHost>

but the effect is, that now every *.png request gets reroutet to fallback.png. it should only happen if the requested is not available.

What can i do?

Thanks a lot!

Ok, found the problem:

it needs to be:

    RewriteEngine On
    RewriteCond %{DOCUMENT_ROOT}/$1 !-f
    RewriteRule ^(.+\.png)$ /tiles/fallback.png [L]
