Many of my eBooks have cover photos that appear
too large,
too small (thumbnail), and/or are
not positioned at the center of the page.
How do I fix that ?
I often change the covers of my eBooks when they are too low-res for my liking. And what happens frequently is that when I add the new cover, it appears as a thumbnail when I open it in Adobe Digital Editions.
On the flip side, by default a lot of the covers of my eBooks are high-res, but do not fit the page.
And lastly, regardless of size a lot covers appear on the left or the right, instead of the center which is what I want.
A perfect cover page for me looks like this:
1. It is placed at the center
2. It fits the entire page
How do I achieve that in Calibre?
Thank you.
PS: Just want to let everyone know that I know nothing about coding. I'm a total newbie to it, and frankly find it very intimidating, so please explain to me like I'm 5 if instructing require coding.
