How about a picture of her next to another human being or something of known size. How tall/heavy was she? She doesn’t look that big and unless she was very tall, I doubt that she’s too big to fit into a standard casket.
Here’s a link to a pic of her standing next to a man. I don’t know his dimensions, though, so I’m not sure how useful it is:

[It’s the pic below the one where they’re in the water. Scroll down a little to see it.]
There’s a photo of her standing next to Neil Abercrombie, who is 5’5” tall. She’s just a little shorter than him, which is why I put her at 5’2”. That’s all in the first post I did about this, at http://butterdezillion.files.wordpress.com/2014/02/did-fuddy-have-an-open-casket-funeral-updated1.pdf
