HELP!!! Callback Troubles!

Hi everyone,

So I am a teenage actor living in Atlanta, and signed with a pretty major agency for my area. I recently self taped for a national commercial for a pretty large brand, and I was very excited when I learned they wanted to do an in-person callback. The callback is tomorrow, when I realized, this is my very first in-person audition/callback, and I have none of my professionally shot photos printed at home. I've read that the industry standard is 8x10 photo paper, but I don't have that, and we can't get it on such short notice.

Is it standard for casting directors to ask for a physical copy of my headshot and resume? What do I do if they ask for it and I don't have it? Thanks!
