So it turns out there are sites that offer stunningly gorgeous and unusual photographs for free that you can do whatever you want to (Creative Commons Zero license) -- including use them on commercial products! Be warned, if you're easily distracted by shinies, this may be a rabbit hole you don't want to jump down. But if you dare, you might find everything you need to make your Zazzle store a whole lot cooler! Check out https://unsplash.com/license for more details. All the designs I use on this store are based on royalty-free images with minimal editing (mostly framing), so feel free to make use of them however you like.
