I used Pic-0.1 to check your pediaicons file and while I saw the missing files it said that I was missing the links for the f-15 and the modern worker too, so I checked it and I found a bug in the original C3C .ini files what is supposed to be corrected with PTW or at least I think so as I found the corrected .ini files in the PTW units folder for f-15 and modern worker.
I think that is a bug in Pic-0.1, or perhaps you have a special version of C3C - there is no Worker or F-15 folder in the Conquests/Art/Units folders, and there isn't supposed to be. The game will find the files just fine if they are in the Civ3PtW/Art/Units folder or even the Civilization III/Art/Units folder.
