Answers
Hello,
There are a few ways to do it but first I need to know something:
Are the images having their width and heights set? Like <img src="" width=""100 height="100" /> because if these values are not being set then you can just change the height or width and the browser will automatically keep the aspect ratio. Is this information enough or do you need to also know how to change the size of the images?
But like Steggs says, if the image is the same size on your pages, just explicitly set the image size in the tag and let the browser do the work. Not if you're looking for thumbnail, and your images are large and performance is an issue, you might want to use a tool to resize them ion the server and only show them.

Put this within the <head></head> section:
<script language="javascript" type="text/javascript">
function resize(which, max) {
var elem = document.getElementById(wh
if (elem == undefined || elem == null) return false;
if (max == undefined) max = 100;
if (elem.width > elem.height) {
if (elem.width > max) elem.width = max;
} else {
if (elem.height > max) elem.height = max;
}
}
</script>
Then load your image like this:
<img id="some_image" onload="resize('some_image
