Apple TV 2 - access image cache

[iMore Question]

I lost all of my photos on my PC and the only pictures of my daughters are on teh apple tv. Please help me access the two apple tvs I have and get these photos.

I read a ton on this, but get confused on the software I need to jailbreak the Apple TV. My understanding is that once it's jailbroke, I can use WINSCP to look in the folders.

Thank you so much.
