Hmmm edito, ya lo coloque y no funca :( , mi problema tal vez es por que tengo varias divs :
<div onmouseover="this.style.backgroundColor='#B3B3B3'" ><div class="DIV104"><a href="http://www.msplinks.com/MDFodHRwOi8vbWVzc2FnaW5nLm15c3BhY2UuY29tL2luZGV4Lm NmbT9mdXNlYWN0aW9uPW1haWwubWVzc2FnZVYzJmZyaWVuZElE PUlE" target="_blank"><img src="http://3.bp.blogspot.com/_uPQRNOJSoQY/TGRCDUhXXuI/AAAAAAAAAvU/E4a84BlNQ6I/s400/TOP1SENDMESSAGE.png" /></a></div></div>
<div class="DIV105"><span class="imagenvideo"><a href="http://www.msplinks.com/MDFodHRwOi8vZnJpZW5kcy5teXNwYWNlLmNvbS9pbmRleC5jZm 0/ZnVzZWFjdGlvbj1pbnZpdGUuYWRkZnJpZW5kX2NvbmZpcm0mc3 RhdHVzQ0Q9MSZmcmllbmRJZD1JRA==" target="_blank"><img src="http://1.bp.blogspot.com/_uPQRNOJSoQY/TGRB9MW6BmI/AAAAAAAAAvM/WKAMBgQ-SjI/s400/TOP1ADDTOFRIENDS.png" /></a></span></div>
y ya cada una de ellas esta posicionada, no se si eso influya:
div.DIV104 {position:absolute; top:824px; left:154px; height:1%; width:30; background:transparent; border-left:0px solid black; border-right:0px solid black; padding-top:4px; padding-left:4px; padding-right:4px;}
div.DIV105 {position:absolute; top:824px; left:440px; height:1%; width:30; background:transparent; border-left:0px solid black; border-right:0px solid black; padding-top:4px; padding-left:4px; padding-right:4px;}
