After you use Photoscan it saves the scan to your phone’s pictures, the easiest is to upload to Dropbox if you already have an account or ImgBB if you don’t then post the share link.
Please use one of our approved hosts such as Dropbox.com or IMGBB.com Both are free and host high res files. You can then create a link and put it in the post.
No, please upload to Ingbb, Dropbox or reddit. Imgur degrades the photos significantly and posts to a public database other people can see and comment on outside this sub.Imgbb is just as easy to upload too, please use that.
There are multiple ones, Hugin is a free/open source one:

For $$$, you can use Photoshop too, or there is PtGui, AutoPano, and who know what else.
But with these old photos, clicking the same detail on different photos is quite unavoidable ("control points").
So is it your page?

I couldn't find the other images in your pano, just one, but I couldn't pair it with anything yet, though a nice full-circular pano could be the best.
