Rp Tutorials

I'm not sure where else to ask, but I've seen the simpleviewer photo galleries used on webs pages before, with pictures of a house and the layout, etc. I downloaded the simpleviewer program as well as Picasa, created the gallery, and when it pulled it up in my web browser it loads just fine. My problem is when I try to get it from my computer to a website. Here are the instructions specific to Picasa, and step four is where I'm having the problems. Where am I supposed to upload it and how exactly do I get the information to put it into a webpage? I'll be using webs.com for it if that makes any difference!

Thank you in advance!
