We found a new interesting website openphotovr.org/ that allows people to "glue" photos together in a kind of panorama, but not exactly. It's easier to try it than to explain it. I did a test with some of my pictures. You can look it here:openphotovr.org/#ZAuh0YIu. (You have to click on the photo to navigate). There are a lot of examples on the left of the page.
The program is open source and it's very new (beta). There are many things that can be improved.
We think it could maybe be interesting to have this feature on hikr.
Who is interested?
