Where do assets for Minecraft mods go?

I found this link: Where do I store (or how do I refer to) textures for custom blocks?

Unfortunately, the answer did not explain where that assets folder actually is. As such, I can't figure out where the textures themselves go.

I'm trying to replicate the tutorial on minecraftforge.net, so the mod's ID is "generic". For some reason, though, the assets folders all contain folders called "genericmod".

Basically: Can someone give me the exact path I should go to, starting from forge_1710_src, to put my graphics in?

forge_1710_src/src/java <--this is where your code lives, possibly inside more directories
