PanoPreviewer

PanoViewer is a plugin for Photoshop (and compatible plugin host applications) which allows users to preview equirectangular images as interactive spherical panoramas within an OpenGL-accelerated window displayed without leaving Photoshop. This is a useful way to assess a panorama before committing to a final conversion to QuicktimeVR or other output formats, as it integrates easily into a Photoshop editing workflow.

PanoViewer is provided free by Pangea Software.
