Pioneer Venus Radar Images Options

[ncc1701d]

I was looking for the best availble radar images from Pioneer Venus
I think I found them here
http://pds-geosciences.wustl.edu/geo/premg.../pvvenus/radar/

but when I use
NASAVIEW found here it would not open them.

http://pds.jpl.nasa.gov/tools/nasa-view.shtml

Anyone know why?
or know of a better place to find the best/highest res of pioneer radar original images from nasa?

thanks

a question bjorn dose the new img2png work on the old img and imq from the `90's - i do not use it so ?
now from the label in the link in the ops post
these are 32 bit
http://pds-geosciences.wustl.edu/geo/premg...ar/pven001a.lbl
if all you want is a map
in a link someplace in my sig there is a rgb png map made from the venus radar data ( oops not there )
http://celestiamotherlode.net/catalog/show...p?addon_id=1100

but PDS-map-a-planet is a great source
also ncc1701d keep in mind that nasaview ONLY will export to a indexed 256 8bit gif

--- edit added too ---
however you might do better with the mg_3002 data
http://pds-geosciences.wustl.edu/missions/.../gxdr/index.htm
the gtdr ( topo),gredr,gedr,
the Global reflectivity data record
http://pds-geosciences.wustl.edu/geo/mgn-v.../mg_3002/gredr/
all 32 tiles
