Someone posted this comment on my Grandma Long Ears picture on Flickr: “hope you get his permission to reproduce this and other pages”

Am I violating any copyrights by posting pictures (including the cover page) of a certain book on flickr and on my blog? I always take the pictures using a camera instead of scanning it, does this make a difference? I’m not using the pictures for any other purposes but solely to share them with whoever may be interested. Now I’m thinking whether it is right to do so.

I would like to hear your views. Please drop me a line here or on Flickr or my email about what you think. If I’m really violating any copyrights, I will stop doing so in the future. Thanks in advance.
