I hope this little explanation is of some use;
If you look at my website homepage (www.actualeducation.co.uk) I have a small tour in the top right hand part of the page. I make my site with a WYSIWYG editor called Incomedia X5. When I am planning the site it lets me select part of the page to be a graphic, part to be a slideshow, part to be text and part to be an html area etc. For my homepage I used a bit of trial and error to get the right size. I found an image which fitted that space perfectly. I tried to put that image on that part of my site and then I used the size of this image (200h x 250w - example). This then let me make a skin for my tour in photoshop which I then used when I made my tour. Using trial and error with the size of an image was easier than doing it with a tour. This image then played no part in my site - it wasn't a pano image - just a standard jpeg which would give me size settings.
I found the size I wanted
Made a skin for tourweaver in photoshop
Used this skin for my tour
Made my tour
Published my tour
Put this tour onto my server - at the root - don't put the files in a folder,
Opened the tourweaver_mytour.html (or similar name on your tour) using notepad
Copied that script
Pasted that script into my website editor (I used the 'this area to be html' thing)
Exported the website
et voila - tour up and NO scroll bars.
Your tour will not be resized if you put it in a big space or a small space. It isn't dynamic. You have to make the skin the exact size you want.
Hope this helps, shout if you need more
