ImageShack, one of the largest media hosting sites on the Web, updated its iPhone app ImageShack Uploader (iTunes link) this morning, unlocking features that enable users to easily share both videos and photos using either ImageShack services and third-party sites like YouTube and Twitter.

ImageShack Uploader 2.0, which is free of charge, lets you record videos and shoot pictures using the iPhone’s camera, and gives you the option to upload them directly to ImageShack servers.

Thanks to further integration with its real-time photo sharing service yfrog, users can also opt to share pictures and videos straight to Twitter, including media that was already stored on the device. Finally, there’s a direct YouTube upload option for videos as well.

A couple of months ago, yfrog also added the ability to snap pictures or record video straight from your Webcam and share it with the world in real-time.
