Hey there

I've set up this rollover state by using <ul> and <li>s. However, I changed some of the elements to floats where initially I used position absolute on the main container, however, since doing this the rollover QR image is no longer working on the hover state but is now static. I really don't know what to do now to get the rollover image to work, letalone to get the google image to float left of the container.
Can someone please guide me as to what I now need to do to get this working correctly? The link is http://www.tagdesign.co.nz/apps-index.html

Thanks in advance.
