How to bulk replace images in EPUB?
Some of the epubs I've bought have .png images. I've been trying to convert and substitute them with their .jpeg equivalent (same file name, different format), but the only way I can seem to be doing so with no hassle is through Calibre Editor using the 'substitute image' option. However, that is quite slow as there's no batch option for doing that, and I have one particular epub that contains 200+ images.
Is there a way I can substitute all of them in one go and still have a functioning epub at the end?
