I created a screen called ImageScreen which extends RawScreen. You can set
this up pretty easily to then load a bytearray image from the database and
call it in your velocity template as:
<img src="$!link.setScreen("img.ImageScreen").addPathInfo("imgId",
$img.imgId)"/>
The doOutput method of the ImageScreen is responsible for writing the
byte[] data to the output stream.
If you need code examples let me know. I have it in my CVS somewhere and
can send it to you offlist.
