Very simple. Name and save your second page as you wish, but the shorter the better. In your case, may I suggest gallery? or even gal can do the trick. Then publish it like you published your main page using the button "publish" on the horizontal up tool bar.
The URL of your second page will be
http://www.domainname.com/gallery.html
while the URL of your first (or main page) is
http://www.domainname.com/index.html
Now you have 2 pages put on the internet. The next step is how to link those 2 pages so the viewer can go back and forth. That's why you need hyperlinks to connect the 2 pages. Hyperlinks can be in forms of buttons, images or texts.
Looks like to me that you already put buttons on your main page. Open it in Bluevoda and double click on buttons. There's always a window with an URL slot. Type in the URL of your second page which is
http://www.domainname.com/gallery.html
Save the main page and re-publish it again. You're done!
There's some more info. You would like to link back your gallery page to the main page right? make another button on your gallery page and type in the URL of your main page :
http://www.domainname.com/index.html or simply
http://www.domain.com (This short form of URL can be applied only for returning to main page).
Save and re-publish it again to make the link work.
Now viewer can go back and forth by hitting buttons. The same principle will apply for more pages to come.
So there's nothing to do with creating a folder or playing with the control panel so far.
The only trick is to play around with buttons and to find wheres the URL slot to type in.
In case of text or images links, hightlight the text or click on image and click on the link button on the up tool bar, the "edit hyperlink" window will open for you.
I hope I am making myself clear enough. Good luck to you:)
