I recently went to a grad party, and my uncle was showing off his new Samsung TV where he could play pre-installed art slideshows on the TV. Now my father thought that was really cool, and asked me if we could do that with our TV, which is an older Samsung, just by a few months. Now I was wondering if there was a way that I could stream my photos from my computer over our home network to the TV via the ethernet port on the back of the TV. Do I need a server for something like that, like what's involved for doing that?
