Is there a vbforums resident geologist?

I've come to you guys/gals for help before, and I have come back to ask yet another question.

that is a picture of a rock (it makes you download it, i don't know why). I need to know what the name of it is. I think that it's an extrusive igneous rock, but i'm not sure.

Any help would be greatly appreciated.
Thanks in advance

My dad would know (Rock Mechanics PhD) but he's on a 5 day straight shift at Inco right now due to the strike... :(

Thanks for the response, but I'm pretty sure I've come to a satisfactory solution...sandstone.
