As to the images, there are many different screen sizes including phones & tablets. You'd be best to use %.

<img alt="whatever" src="whatever.png" height="50%"/>

The problem is that without a Reader, you won't be seeing what someone with a Reader will see. So get one and test away but it has to be high resolution and a Kobo would be better than a Kindle since your source is ePub. I suggest the Kobo Aura H2O.

Thanks, JSWolf.

I'm pretty sure that the images are not high resolution. I don't know about that kind of stuff. They're probably 72 PPI. In terms of pixels, they range from 300px to 600px.

Does this mean that they will look terrible on high-res screens?

I'm worried about my images now! For testing purposes, I only have a small Android tablet and my mobile phone, both with Google Play Books.

My ebook is fitness-related. Most of the images are tables. I'm assuming that most of my readers will read the ebook on their phones.

How exactly do you recommend that I code the images? At the moment, they look like this:

<div class="centerimg">
<img src="whatever.png" alt="Whatever"/>
</div>

.centerimg {
    text-align: center;
    padding: 0;
    margin: 6pt 0 16pt 0;
    }

Some images have height and width set in numerals (e.g. width="600" height="400").

I thank you for your guidance.
