The JVM is notorious for caching images.  While this
is usually a help for inexperienced programmers, it is
a hindrance for anything else.

Doing an image slideshow, the only way I found to avoid
image caccing was to load it into a  byte[] array anf use
the constructor that accepts a byte array.

I do not know if that is practical for your DB.
