PhotoNavigator is designed to work with [Adobe Photoshop 3.0.4][1] &
newer. It also bears a striking resemblance to the "Navigator" palette
which appeared in Photoshop from version 4.0 onwards - I would not be
surprised to discover if Adobe bought the rights to PhotoNavigator and
added it to Photoshop, as it is almost identical to Photoshop's
Navigator palette in form and function.

Note: Because Adobe introduced it's own navigator in Photoshop version
4.0 and onwards; This plug-in is obsoleted by that version and later,
and is therefore limited to using in Photoshop versions 3.0.4 & 3.0.5,
only. That is, you can likely use this in newer versions of Photoshop,
but there is little point in doing so.
