1. I wanted to create 360x180 images to be uploaded to http://www.360cities.net/. Will Autopanogiga allow me to do that? Will the outputs of AutoPanoGiga be directly uploaded to 360cities.net?
I´m not sure to fully understand what you mean. Do you want to have a "push once does it all" solution? AutopanoGiga is a stitcher. Stitchers stitch and render an equirectangular image (or what you want them to render).That´s it.
I don´t know whether there are apps which also upload the images to a server automatically.
If you want something you´ve never had, then you´ve got to do something you´ve never done.
