New tech icons! And, aren't the icons supposed to be the color of their type?

Here they are, all set as pcxs and with the smax palette. No blanks.

Okay, here's how to do it in GIMP. 

The problem last night is that I'm not feeling well, and forgot that GIMP has a problem with pasting in the transparent background color, which is what I did.  Instead, it's a simple matter of making the 215x215 window from a source of unaltered, smax-paletted background, like one of the official faction .pcxs:



Note that the selection was exactly 215x, like the original.  Now go back to an open copy of the tech file and add a tranparent layer:



Select the Select by Color Tool:



Click on the background color:



Hit delete:



Now, select all, and paste it into the blank background.  Save as, in this case, tech070.pcx.  I've attached the results, redundant as they may be, to prove this works.

Excellent!  I'll give that a try when I'm not half-asleep.
Your approach really didn't differ that much from the one I used.  The only difference, besides how I handled the background, is that I used the "Color to Alpha" tool under the Layers-->Transparency menu.  Nevertheless I can see that they work properly now.  Thank you!
