Eye-Fi: Add Wi-Fi To Digital Camera

The Eye-Fi is an Wireless SD memory card that adds Wi-Fi to any camera that supports SD memory card. It can automatically upload pictures from your digital camera to your PC or Mac and to your favorite photo sharing, printing, blogging or social networking site.

The Eye-Fi is like any other SD card, except that there is some setup to do first. Once that is all done, the point of the Eye-Fi is to upload your photos while your camera is on and connected your wireless network to one of the many supported photo sharing services and/or your computer. It appears as though Eye-Fi is aiming to make repetitive card readings and fiddling with a USB cable things of the past.

Setting up the Eye-Fi is fairly simple but involves installing local software on your Mac/PC (no Linux support) which receives settings from an Eye.fi account you must create. The first step is plugging the Eye-Fi with its included SD card reader into your computer. From there, you find the appropriate installer for your OS then install and run it.
