Hi Andy
In this case, you have to provide a servlet (e.g. uk.co.demon.ajsoft.Images), which
delivers images.
Then your HTML tag will be somthing like:
<IMG SRC="/servlets/uk.co.demon.ajsoft.Images?name=delete.gif">
But the problem with this is, that the Image class has to know, where to search for
images.
Servlets normally don't know their home directory.
The only way to specify this, is via an initialisation property.
