pondering

An interesting article in an Aussie mag I picked up yesterday (Scrapbook Creations, No23) about copyright and scraplifting. It got me to thinking about all the web-publishing going on with these blogs of ours. Do designers object to having their previews copied to our blogs? What is the etiquette for sharing an awesome layout by someone else that really inspires? Technically, if I find a pic of something I really gotta have from the Target or House catalogue, can I post it here? No answers, just wondering out loud.
