Hi all,
I'm currently reading an epub that has a lot of equations. They're all typset as images. Problem is that images are completely unreadable on screen. They're so small. I'm using kobo.epub format so you can double-tap on an image to enlarge it. But that takes way too long since sometime I misstap images due to their small size.

I've been looking at KoboTouchExtended plugin and also have looked at covert options in Calibre but don't see an obvious way to enlarge them.

I did notice Search & Replace in Calibre's conversion options so could I somehow change each img tag to include a larger size somehow? Is anyone familiar with CSS that Kobo supports which would properly enlarge each image by 200% or something like that?

Anyone have some suggestions?

Thanks!
