(As per link:https://issues.apache.org/jira/browse/ISIS-1604[ISIS-1604]), SVG images can be used:

* as Logo in the upper left corner (Wicket Menubar)
* on the Login Page (`login.html`)
* as favicon (`image/svg+xml`, cf. link:https://issues.apache.org/jira/browse/ISIS-1115[ISIS-1115])

However, SVGs are not, by default, displayed on the welcome page.
SVGs can be attached as ``Blob``s, but they are displayed as bitmaps (by means of the Batik rasterizer) and do not scale.
The rasterizer (of course) can not deal with animations (cf. attachment).

To fix this, you can add the following dependencies:

[source,xml]
----
<dependency>
    <groupId>com.twelvemonkeys.imageio</groupId>
    <artifactId>imageio-batik</artifactId> <!-- svg -->
    <version>3.3.2</version>
</dependency>
<dependency>
    <groupId>com.twelvemonkeys.imageio</groupId>
    <artifactId>imageio-batik</artifactId> <!-- svg -->
    <version>3.3.2</version>
    <type>test-jar</type>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>org.apache.xmlgraphics</groupId>
    <artifactId>batik-transcoder</artifactId>
    <version>1.8</version>
</dependency>
----

However, *please note* that these dependencies have high CVE values, and so may constitute a security risk.
