Camera without Wi-fi? No probs, there is Eye-fi.
Wi-fi is gradually becoming a part of point-and-shoot cameras, but not DSLRS. If you wish to add the feature to your existing camera, just buy a Eye-fi card. These are nothing but SD cards with a built-in Wi-fi antenna. But a Wi-fi enabled Eye-fi card has to be paired with a computer first. Once done, it directly upload images on the web. The only drawback with such an additional accessory is that as it is not embedded in the camera and the display doesn’t show the Wi-fi connectivity option.
