I even tried switching from mobi to azw3 to see if perhaps something got lost in the conversion from epub due to the older mobi format.

I'm guessing I need to enable "Panel View" for each page, but sadly I don't see that option for mobi/azw3 settings. How is that "enabled" physically in the ebook anyway?

I spent some type looking at the css of the source epub, tried modifying the "image" class and was dumbfounded to why it didn't affect the image. Then I realized that the "image" class only affected the <p> tag.

Now I can either add a "height=100%" to all of the <img> tags, add a "img" class to the css (may affect more images than intended), or create myself a new class (eg: class="imagepage"). But don't think I'm some css genius as I just use google for help on that and I'm basically a html 1.0 guy.

It seems rather silly for ebooks to have a fixed-resolution mentality in their creation. I see options in Calibre to adjust text in the conversion, but really nothing for graphics. Maybe add some logic on when to modify a page to upscale image / enable Panel View? Like if the page no text but one large graphic?
