How to remove all JPG but keep PNG of a EPUB? Maybe there is a way to access the EBUP folder to mass delete the JPG files?

Additional Info
- I am able to manually remove the JPG, I just would like to do it faster.
- File is an DRM-free EPUB
- I am using calibre 3.6 on OS X 10.11 El Capitan
- The PNG contain useful diagramms while the JPG contain additional fotos, which I don’t need and just use a lot of space. I am already using caliber’s image compression feature.

I haven’t found this specific topic in the documentation nor in previous posts, but if I have missed it please link to it. Thank you for the mobileread and Calibe communities. They add a lot of value to my life.
