You wanted it - here you go. Don't be surprised if any of them are appalling to look at; there's a reason I dumped them in a folder like this.
You do not have to credit me with anything, but if you could link me to your edits or whatever, I would like to see what you make with them. Please do try to give credit to the vector artists, though. If you are unsure who made a vector in one of them, feel free to ask me.
Also, I decided to mix in some non-pony ones among the pony.
EDIT: Okay, here's an alternate download link: mega.co.nz/#!zEgAkJya!LCKEriH3…
Oh wow, can't even download :c
Why's that? O.o
Glad you decided to give these out, some of them are good starting points.
As if I wouldn't credit you. I'm gonna try to give some new life to some of these next week probably!
