When Poser changed from using .rsr library thumbnails to using .png library thumbnails, Poser converted these thumbnails from .rsr to .png automatically in any library that I looked at in Poser. Now, this seems to have stopped happening.

I have looked though my old library of models etc that I have made, and it seems that in many of the .zip forms of my older models etc, the thumbnails are still in .rsr format, which is no use to another user using my models if his Poser has stopped auto-converting from .rsr to .png.. How can I convert these .rsr images to .png mode on my computer, without having to load every model etc involved to stage and re-save it?

Can P3dO Explorer help me here?

I have been using Poser from Poser 3 on.
