I just had a careful look at those reports myself, and compared them to the original image files. It seems some of them are converted to .png for some reason, despite ALL images originally being .jpg. These png files are the ones taking up most of the space.

Even in the earlier 21mb Epub, some images were converted to png, but not as many as in the newer one. I suspect this is what's making the file size so large. Is there a way to change them back to jpg through Sigil?

PS: Is it not possible to edit posts here? I couldn't find an Edit button anywhere. And I do apologise if this post appears twice, as I'd submitted it once and it didn't appear in the forum for some reason, so I'm posting it again.
