Tom,

these ideas may help - or not....

if you know the ID of an element, you can get it's height
like below. But from quick testing it only works if the
height is explicit and inline;

document.getElementById('IDname').getAttribute('height')

You can also try this;

document.getElementsByTagName('img').item(0).getAttribute('height')

e.g. you could use this to get an array of image
heights (not tested)

imgHeights = new Array();

for (var i=0;i<document.images.length;i++){
imgHeights[i]=document.getElementsByTagName('img').item(i).getAttribute('height');
}

getting properties out of stlyesheets becomes more involved.

of doing this here;
