Stu I have the Paperwhite and you can see them but they are very small. Also the text is grey, not black.
Brian I found I had to make the text bold on my paperwhite, and the pictures were hard to read, but I would use my iPhone for the pics. this worked well.
Cathy I was able to on my nook, so I would think they would be viewable on the kindle as well, but I don't know for sure.
Dainey On my Kindle Voyage the pictures were clear and reasonably sized, although in black and white.
