well, there are four techniques to use:a.) use HTML to hard code the width and height of all images - thus requiring all users to upload the profile image of the same width and height.b.) use php (in this case since you indicate its use) to determine if the image width and height exceeds your requirements and if so, use hard coded width and height values - ignoring the actual - otherwise use the actual wdith and heightc.) check the file when uploaded to prevent it from being to large based on your requirementd.) automatically resize uploaded images if they exceed your requirements

You can use this function to get the size of an image:http://www.php.net/manual/en/function.getimagesize.phpYou can use this function to create a resized image:http://www.php.net/manual/en/function.imagecopyresampled.phpCheck the examples to see how they're used. I'm not sure if you can use getimagesize with a URL or if the image has to be a local file.
