You're mixing things. The thread you referenced is about something else. It's about RTF output and FOP 0.91beta/Trunk. Since you're talking about a Driver object, you're still on FOP 0.20.5 where the image cache works differently.
See http://xmlgraphics.apache.org/fop/0.20.5/graphics.html#caching on how to reset the image cache in FOP 0.20.5 between rendering runs. Note that this function is not available anymore in the latest version since there the cache works differently. It has much better memory reclaiming abilities (using weak references) so a cache reset method should not be necessary if you use unique URLs. On the other side, if anyone submits a patch to retrofit this method we will surely consider adding it. However, I'd prefer an extension attribute on fo:external-graphic that signals FOP to bypass the image cache entirely. To answer you question about "where" the image cache is: It's held by a static variable so it is tied to the class loader that loaded the FopImageFactory class.
