Mobile software developers bepilot has released FlickR upload utility for Windows Mobile powered Smartphones under the name zipPhoto. With this utility you can take photos with your MS Smartphone device and upload them directly from your smartphone to your FlickR photo archiving service.

Wish you can share your cameraphone's photos right away without having to get home and copy them from your phones memory? Well now you can with zipPhoto. Just point, shoot and upload! zipPhoto allows you to take a photo and directly upload to your flickr account...instantly! Plus you can set the photo's title, description, and tags all before you upload. said the developers.

Note that this application only works for users who use the old method of logging in to Flickr and was built for Windows Mobile 5 phones, but should run on older smartphones too if you have installed .NET CF V2.
