I don't know if it's the right place to ask, but of all the plugins, this is the one I think this would fit best in, unless there was a completely new plugin designed for it.

I've gotten ahold of several epubs lately that have all images were in png or bmp format. Bringing the size of the book to well over 100mb. I know that converting the books to mobi and then back to epub (usually) will fix the png's and convert everything to jpg. This did work and generally brought the book to a much better size (~10-20mb). However, after searching the internet and the forums, I cannot find any other way to do this other than manually. If there's another way and someone knows of it, I'd appreciate it. I ran across a single thread about an android program that's supposed to do it, but I'm looking for something in windows.

Could this be something added to this Quality Check plugin - if it's not too difficult? It's not really quality check, but some of the 'options' in your plugin don't really fall into the category either, and it is sort of 'cleaning' the book up (in size).

Anyway, I appreciate the consideration of this, even though it's not likely to be added, but better to ask than to never know.
