Friendship is Magic voice actors

What you see here is a modified version of the page at [link] (as it was at the end of 2011. More voice actors have been added to the show since then, like Britt McKillip and Erin Mathews.)

This is what I did to modify it, using only Microsoft (Windows) Paint:
I rearranged all of the photos to first be in the order their names are in the credits (the first twelve), and then by approximate order of prominence by roles they play on the show. Some of the people didn't have photos, or even entries, on BTVA, so I had to get those images myself and edit them into the 120x137 boxes.

For some of them, I had to type new captions (names). Every actor and actress in this list has done at least one voice for "My Little Pony: Friendship is Magic". Can you identify each person's role(s)?

I should mention here that Jayson Thiessen does not (or hasn't yet) voice(d) any characters on the show, but I included him because he's the current show director and those cutouts of him and Wootie are from the same photo.
Edit: Guess what? Jayson does do two voices on the show! He's Celestia's royal guards, and the security guard from "Read it and Weep".

Additionally, Emily Hampshire is only a guess (as Bon Bon's voice in "Call of the Cutie"), and when I think about it, it's possible that Tabitha St. Germain voiced Bon Bon in this scene, just like in "Lesson Zero" and "The Super Speedy Cider Squeezy 6000." In "Green Isn't Your Color", her voice sounds more like Tara Strong.
