Does anyone know which version(s) of poser converted RSR to png?

I reinstalled Poser 8 (no patches), but that didn't help. I know 2012 doesn't do it. But, I can't remember if it was a particular patch to 8 that made it possible or if it was a particular patch to 7 that stopped it. 

If anyone knows, please let me know. I'd greatly appreciate it:)
