How do you edit your Pokedex's Skin?

["StruttingPhil"]

I have looked around and I cannot find anyone that explains this in detail. Does anyone know how to do this and what programs you use to either convert an image to something the save file would be able to use, or what program you would use to put a new image into your save file? And if this be done in both BW and B2W2 if it is possible.

Use PokeCGear.

It's a part of Pokestock with which you can edit your CGear and Pokedex skins.

It's possible in BW and BW2.
