Seems that you haven't done important thing. These pictures contain only large images of components. The small ones are in components.bmp file (it is usually in the bottom of the folder if you use windows explorer). There you will see small images of all components in one large picture. You need to make new small pictures for your components (be careful of the size for the small component picture) and place them in correct slot. E.g. component #275 MUST be in exactly #275 position in that file (it goes from left to right). The best program to edit this is ACDSee.

Hope this helps, and don't hesitate to ask more if this isn't enough. I have been making large tech mod and added a lot more pictures (however, these are just a different color variations of already existing ones).
