[LCS] Location billboards textures?

[QallMeQ]

First of all; I've got no idea if this topic is in the right subforum. But as Liberty City Stories is a III-era game, I'll post it here. If a mod could move it to another subforum which fits the topic better that would be allright with me :x

 

I've extracted ''GTA3PS2.IMG'' from a ps2 .iso-file of LCS. I went through all of the 500+ .CHK-directories in search for the textures of various billboards in the game. I only managed to find the ''Madd Dog - Still Mad''-poster. Does anyone know where I can find textures of billboards and posters around the city like the ones on the screens below?
