Just something I figured out on my own - you have to move the files out of your "web" folder (or the equivalent) and place them in your site folder. I also came to the conclusion that you don't use the index.html file if your site already has that name used. I renamed mine "indexg.html" for the gallery folder - but I'm using frames. The one thing I'm coming here to learn is how to center the viewer in the frame (or on the page, for that matter) in my coding.
That's all figured out - but when I tried the instructions on how to embed using Dreamweaver, I got hopelessly lost. I ended up doing it the way I described above - and while I was at it, simply defined the page margins and now my player is set up just where I wanted it to be in the frame.
I've learned all of this from scratch - (ing my head, that is). I thank these forums and the support of the SimpleViewer staff in helping with guidance, however - since it kept me going and helps me learn more.
