Is it possible to add wordpress gallery slideshow on Google Sites?

Q: I'm hoping it is possible to obtain instructions on how to upload and implement your file in google sites where I don't have direct access to ftp or the root directory.

Your tool looks wonderfully useful for my front page to bring a dynamic interactive feel to my new site, which I am building with Google, instead of my current site which is built with frontpage and hosted on my server.

If this would be easy to implement in Google, I will probably buy the commercial version so I can pull your tagline off and use it for the website.

A: It's possible to add wowslider on Google Sites using "Gadgets for Google Sites":
