I have added custom code in suffusion-subscription.php to change the image of a Facebook icon when the mouse is hovering on the image.
During initial load, no image shows up. After that mouseHover and mouseOut event shows appropriate images but not on initial load.
The following image shows the issue:

JavaScript:
//preload images:
fb1 = new Image(64,64);
fb1.src = "http://sohamshah.com/wordpress/wp-content/themes/suffusion/images/follow/Facebook-04.png";
fb2 = new Image(64,64);
fb2.src = "http://sohamshah.com/wordpress/wp-content/uploads/2011/11/fb-broken.png";
//image swapping function:
function hiLite(imgDocID, imgObjName, comment) {
document.images[imgDocID].src = eval(imgObjName + ".src");
window.status = comment; return true;
}
</script>
HTML:
<div class='fix'>
<a href="http://feeds.feedburner.com/sohamshah" class="follow-icon-and-tag" title="RSS">
<img src="http://sohamshah.com/wordpress/wp-content/themes/suffusion/images/follow/RSS-13.png" alt="RSS" style='width: 64px; height: 64px;' />
</a>
<a href="http://www.facebook.com/soham100" onMouseOver="hiLite('fb','fb2','Follow Me on FaceBook')" onMouseOut="hiLite('fb','fb1','')" class="follow-icon-and-tag" title="Facebook">
<img name="fb" "src="http://sohamshah.com/wordpress/wp-content/themes/suffusion/images/follow/Facebook-04.png" alt="Facebook" style='width: 64px; height: 64px;' />
</a>
<a href="http://twitter.com/sohamshah" class="follow-icon-and-tag" title="Twitter">
<img src="http://sohamshah.com/wordpress/wp-content/themes/suffusion/images/follow/Twitter-08.png" alt="RSS" style='width: 64px; height: 64px;' />
</a>
</div>
Any help in this matter will be appreciated.

There is an extra double quote next to src in the image tag.
