ok, so the .flc files (animations) are correct and in the right places.
There is just a problem with the .pcx files. Did the leaderhead you download come with .pcx files? There should be art files with names like:
BR_all
IncaLarge
IncaSmall
BR
BR_ANG
BR_CONQ
BR_CONQ_L
etc., etc.
Make sure you have these files, they are in the correct folders, and they are cross-referenced in the pedialicons.txt file (check the spelling, as one typo will cause a problem), and the entries are grouped with the other civs (like all the _ANG entries should be together, you'll see this by looking at the other entries). The last part of the name (.pcx) you need to type in the pedialicons.txt file, but the files themselves in the art folder do not need the .pcx at the end.
I also like to keep all the names exactly the same, like for the Incas, I make sure the civ is called 'Inca' everywhere, and all entries say 'Inca' not 'Incas' or 'Incans'.
In the editor under the civilazations tab, you should have 'Race_Inca' in the civlopedia box.
Are you using PTW or Civ3 v1.29f?
If using PTW, make sure you've created a folder inside your scenarios folder that is the name of your mod, and put an art folder and a text folder inside your mod's folder, with the necessary folders and files inside these.
Inside your art folder you should make new folders so they will be broken down like this:
Civ3PTW
-Scenarios
---Your mod's folder
------
ART
---------Advisors (the _all files)
---------Civlopedia
------------Icons
---------------Races (Incalarge, Incasmall files)
---------------Units
---------Flics (the .flc files)
---------Leaderheads (all the other files, like _ANG, _CULT, etc.)
---------Units
---Your mod's .bix file
And under scenario properties for the part where it says 'scenario search folder' you have the name of your mod's folder.
I hope this helps and isn't too confusing
