Mashable has just posted a great piece, 26 Places to Find Free Multimedia for Your Blog.
I’ve already included many of the resources they list in The Best Online Sources For Images and The Best Places To Get Royalty-Free Music & Sound Effects. However, they also listed some sites that are new to me, especially the ones that have freely-available video (I didn’t include any video sources in my lists).
I’m also sure that a ton of additional sources will be accumulating in their comments sections. Because of that, for now, instead of just selectively adding some of their sites to my lists, I’m going to include a link to their post on both them.
