Wireless memory card maker Eye-Fi yesterday announced that it is extending support for users’ video uploads to popular online photo-and video-sharing sites Picasa Web Albums, Photobucket, and SmugMug.

Eye-Fi’s patent-pending technology works with Wi-Fi networks to automatically send photos and videos from a digital camera to online, in-home and retail destinations.

Users of the 4GB Eye-Fi Share Video and Eye-Fi Explore Video cards can upload videos and photos automatically, wirelessly, and directly to their albums on those sites, as well as over twenty other photo and video sharing sites.

“Many of our users were already automatically uploading their photos to Picasa Web Albums with their Eye-Fi cards and now can upload videos just as effortlessly, directly to their albums,” said Brian Axe, director of product management at Google, parent company of Picasa.

The Eye-Fi Explore Video card automatically geotags photos and videos with information about the location where the picture or video was taken. The card also and offers hotspot access from more than 10,000 Wayport and open hotspot locations in the U.S., when users are uploading content away from home.

Eye-Fi’s newest wireless SD memory cards are now available (at Apple and Best Buy stores, among others) nationwide for $79 (4GB Eye-Fi Share Video) and $99 (4GB Eye-Fi Explore Video).
