Historical and Background Info
Questions about how to create a panoramic photo are certainly on topic. Here are such examples:

Initially I was confused about your question. I couldn't figure out if you wanted to know. Based on this excerpt "What is the simplest way to create a custom Google Streetview panorama?", I thought the actual slicing of images to prepare them for the presentation was the key question, so I didn't vote to close initially.
So to answer your question, are questions about the presentation of images on topic?
They can be. But they also may not be. What if this question was about what type of nail to use to hang a panoramic frame weighing 22lbs on the wall in your home? I see this as a similarly off topic vein. That would be appropriate on the diy stack exchange site. Similarly I see the details beyond image preparation on this question being on topic on something like stackoverflow(or some other SE site, or no SE site, just not this one).
Further, as a future suggestion, if you want additional answers, marking your own answer as "accepted" seems like a poor choice. Based on your comments you were hoping for more answers to this currently closed question. If you wanted more answers, not marking your own as accepted would be advised by me.
