Cache of others skins?

I've been wondering.

Most games with custom content cache the custom content from others somewhere. Is there a way to find the custom skins of others somewhere in the Minecraft folder after you played online with others?

Basically, when I see a cool skin someone I'm playing with is wearing, I would sometimes like to "steal" it.

Solution 1:

No, skins are cached in memory, however you can view other skins at: http://s3.amazonaws.com/MinecraftSkins/[USERNAME].png

E.g. My skin would be at http://s3.amazonaws.com/MinecraftSkins/mike4560.png

Solution 2:

Go to nameMC.com then search your username and BOOM! There it is, ripe for the download.
