For tall thin images or tall images with captions I use the following CSS. It should work uniformly on ADE and iBooks and other devices.
First you need to wrap a div around your image
HTML:
Code:
<div class="tallImage">
<img alt="" src="../Images/image.jpg" /></p>
</div>
And this CSS:
Code:
div.tallImage {
width:80%;
height:auto;
page-break-inside: avoid;
margin-left:10%;
}
img {
max-width:100%;
height:auto;
}
The matching width and margin-left forces iBooks to resize the image. You can make these smaller or larger depending on the size of your image. Remember always to test!
