We have, with the last several pieces at least, been making our panoramics to meet up at the left and right edges so that the image is a complete 360° view. This means that it actually works best when you can kind of "immerse" yourself in the image.
I find that the old school QuickTimeVR format works great for this so i always make one for each panoramic that we make 360°.
I made it pretty large, so its more than a 3MB download.
