Sorry, the WMS Client for Arcview 3 doesn't support transparent images yet.  We
plan to add this functionality to the Pro version.

In the meantime you can fool it into creating a transparent layer.  

This example works with the "Mars Landings.ogc" and "Mars Topography.ogc" that
were installed in the Examples folder with the latest beta.  Load those two
files as separate themes, then select the Mars Landings.ogc theme.  

Open the Image Legend Editor by double clicking on the "Mars Landings.ogc"
theme.  Select "Single Band" then click the colormap button.  Press the Nominal
button.  Now the second color in the list should be white. Now set the white
color to be transparent by double clicking on the white color and selecting X
(the first color, white with an X through it) color in the colormap.  

Now you should be able to view the landings over top of the topography.

That's the right location. The .bip file contains the image in RAW RGB format.  

To open them in PSP8 you would have to select the RAW image type then manually
enter the width/height, color channels and file structure information.  This is
easily done, most of the information you need is stored in the associated
.hdr file.   

For now all the information except the width/height is the same for all
.bip images the extension creates.  Color channels should be set to "Three Channel
RGB", Header Size is 0, "Interleaved (RGB RGB ..." should be selected. The order
should be "Order RGB" and "Flipped (bottom up)" should NOT be selected.
