Mouseover hand on images

[Wizardjv]

After adding some images the little hand mousover affect doesnt show on them. I was wondering if anyone new what was causing the mouseover on the whole board? I am looking to add mouseover to certain images, but I cant seem to find in the CSS where this is already done for the board. I would appreciate it if anyone could point it out or help me the code..i am embedding some flash that I would like to be able to add this too.

example

<center><a href="http://www.something.com" target="_blank"><object width="600" height="120"><param name="movie" value="http://www.something.com/ad.swf"></param><param name="wmode" value="transparent"></param><embed src="http://www.something.com/ad.swf" type="application/x-shockwave-flash" wmode="transparent" width="600" height="120"></embed></object></a>
</center>

I have tryed adding on mousover to the code...But doesnt seem to work was wodnering if there is something I could put around it to get the affect or maybe in it? But for some reason I cant figure this out and its bothering me

Thank you ahead of time for the help
