Topic: Installing tiltviewer?!

Hi everyone I'm new here, quite new to web designing, software etc... but I have my own website for which I use to advertise myself,  and I am in the process of updating it, and wanted to use the tilt viewer to show case my images, so i downloaded Picasa, and the tiltviewer download from someones site (paul..? thx  lol ) But I am lost, not sure where to go from there. That is all that is left to do to my site, is my portfolio... I would really appreciate if someone could help me out, as otherwise I'll end up going back to basic HTML and although it will look ok, will not have the desired effect I was going for!

Someone please help...

Regards
Jennifer
