This should work:
<img src="${asset:context:images/some_image.gif}"/>
The value inside a ${...} expansion is actual a binding in disguise,
so it can use binding prefixes such as "prop:" (the default),
"message:" or "asset:".
However, inside a template, the "current location" is on the classpath
(i.e., relative to your component's Java class file), so you have to
specify "context:" to have the path interpreted as relative to the web
application root. It seems a little odd when the template file is
itself in the web root, but I opted for a rule that is consistent
across application pages, components and pages in libraries.
