To make SVG work, both the browser and the server need to support it:
Browser support
- Firefox 3 does not natively support it
- IE9 does
Server support
Apache needs the following settings, either in httpd.conf or .htaccess:
AddType image/svg+xml svg svgz AddEncoding gzip svgz
Supplying different images for unsupported browsers
If you have similarly-named bitmap images that can be used instead for browsers that don’t support SVG, add to httpd.conf or .htaccess:
RewriteEngine on
RewriteCond %{HTTP_USER_AGENT} Firefox/3.*
RewriteRule ^(.*).svg$ $1.png [L]
This example detects Firefox 3 and replaces any SVG file with a PNG file of the same name.
