looking for viewer tiff/tfw

Hi list,
i have some dvd's with tiff/tfw/eck/akt viewable with arcview.
Can anyone recommend a simple tools make the maps viewable with linux ?
(i know i can see tiff with xv)
I am aware that grass can handle them but I am not a gis expert, and 
additionally the usual lack of time.

Ultimately i need these maps as background for measurements. i know 
there are some free solutions out there but i am missing background 
knowledge.
any recommendations ?

re,
  walter
