Data with the type of label that you mention is in NASA PDS format
('Planetary Data System') and can be read directly by IMDISP and also
VICAR. Under Unix the 'xv' image display program has an extension for
PDS files. Note by the way that the label may be either in a separate
file (in which case, one of the fields is a pointer to the actual data
file) or at the start of the data itself.

A number of programs use '.img' as an extension, so it's impossible
to tell you offhand how to read it. Have you eyeballed the file with
a file viewer? You may get lucky and find a readable header in there.
Alternatively, you could try feeding it to one of the image file format
converters such as ImageMagick or HiJaak and see what they make of the
file.

Welcome to the world of standard image file formats....
