What type of texture map is this?

Hey guys, I just need some help here. I need to identify what sort of texture map this is (In terms of ‘texture map’ I mean a bump map, opacity map, etc.) I know it’s not a bump map, because I know what one looks like. The reason I’m asking is because I need to add it to a project in 3ds Max. Here’s the picture:[ATTACH=CONFIG]144774[/ATTACH]
What is it? Please help!

Actually, I think it’s a specular map or any other map that shines. I seem to solve a lot of my questions after I post them for some reason, lol. I guess it’s a good thing.http://bafull.cgcookie.netdna-cdn.com/images/smilies/sago/yes.gif
