Ajax autocomplete DHTML with pictures

I have currently an ajax autocomplete with pictures but it should be changed to look like the firefox search bar. Data comes from an asp.net webservice. Pictures in attached word document. Upon pressing enter the data should be posted to an aspx page. When pressing enter if there is an item selected in the dropdown box the data from this selection should be posted to the searchpage. What should be added : busy animated gif in front of search when searching Layout exactly the same as the firefox search “bold/highlighting?? of what is found (like the “lan?? part)
