Open Mac screenshot on Fedora

[Hannes Mayer]

Hi all!

I just got a few screenshots produced on a Mac (OS 9 ?).
Those are files without any extension - I tried to open
them with GIMP, but it said it cannot recognize the file-
format.
Viewing the files with the krusader editor shows no
header - I was hoping to see some info about the format
in the header.

Does anyone have ideas how to open these screenshots ?

Thanks & best regards,
Hannes.
