Real image width with Javascript
<p>I have the next function:</p>

<pre><code>function setImagesWidth(id,width) {
    var images = document.getElementById(id).getElementsByTagName("img");
    for(var i = 0; i &lt; images.length;i++) {
        // If the real width is bigger than width parameter
            images[i].style.width=width;    
        //}         
    }       
}
</code></pre>

<p>I would like to set the css width attribute of all my img tags to a particular value only when the image real width is bigger than the attribute value. If it is possible, i would like a solution which does not use any particular framework. </p>

<p>Thanks in advanced!</p>

<hr>

<p>images[i].offsetWidth returns 111 for an image of 109px width. Is this because 1px each side border? </p>
