Trouble? If you are running Internet Explorer version 8 or earlier, you will not see
a semi-transparent effect applied to the two bottom photos.
Versions of Internet Explorer before version 9 do not support the opacity property. To
support earlier versions of Internet Explorer, you can set the opacity of the entire object
using the Alpha ilter
Alpha(opacity= value )
where value ranges from 0 (transparent) to 100 (opaque).
