Facebook has announced the launch of 3 new features for Photos:

• high resolution images (storing bigger pictures) – from the beginning of October facebook have been rolling out support for print-quality, high-resolution photos – increasing the size of the photos stored from 720 pixels to 2048 pixels on the largest side or 8 times bigger overall
• a brand new viewer for browsing photos – A better photo viewer makes it simpler and faster to navigate photos.  You can now view photos and even whole albums without going to a new page.  Paging through photos should also be significantly faster

  

• a new uploader with better tagging – a new Flash based uploader allows you to tag multiple photos in the same album at the same time. It will also be easier to tag photos of the same person.

These new features are expected to be rolled out to all Facebook members over the next month or so.
