Images not on tape.

[Richard Nairn]

I am trying to import some spot and landsat thematic maps into grass
but they are not on tape.  They are 24bit images that I am trying to
deal with. Is there a way to import them without losing the quality. I
have tried various r.in. programs but they will not import them.  The
images are not from tape as they have been edited and can be saved
many different formats...

Any suggestions?
