You've probably heard of the Eye-Fi SD card that enables wireless photo sync between your camera and computer. However, with a few extra lines of code you can actually stream all your photos live to the internet for anyone to see.
This setup takes the Eye-Fi one step further. Instead of just syncing it to a folder on your computer, it syncs it to a web server so you can automatically post your photos online. It's cool if you want to keep your new photos shared with friends and family, liveblog an event, or even use an old camera as a sort of security system for your house. It takes a little bit of code, but the Instructable will walk you through every step of the process, so hit the link to see the full how-to (and check out the video above to see it in action).
