These are frightenly easy to do :)
1) Open the 360x180 degrees image in Photoshop
2) duplicate the image into a new layer 2 (e.g. Select All, Copy, Paste)
3) mirror that layer 2 so that it's "bottom up" (what originally was the lower edge,
including tripod, is now on top, and vice versa)
4) erase the tripod by deleting the part of layer 2 where the tripod is visible (now
on top of the image)
5) scale the layer by using Command-(=Apple-) T, then dragging the top handle
downwards until you're happy with it :)
6) save as image.
In short, duplicate image, flip along the horizon, scale vertically, use that to
cover the lower part with the tripod...
Or, even better (a pre-made photoshop action), look at

(the link above SHOULD be one very long line, or it won't work...)
