Flickr may be the most popular picture site on the Internet, but there isn’t a built-in way in Android to upload photos to Flickr. You can e-mail pictures to Flickr and AppBrain shows several pages of Android apps, some of them free, that work with Flickr. The Flickr mobile web site (m.flickr.com) has recently been updated and it now includes the ability to upload photos and video. Uploading works very well on Wi-Fi and 3G and you can select pictures from the Android gallery. Unfortunately, you can only upload one picture at a time. The mobile web site also takes advantage of Android’s location awareness to show you pictures that have been taken near your location and you can also view pictures taken by others.
