Google recently released Mac OS X beta software that lets Apple users upload pictures to the company's image-sharing service.

The Picasa Web Albums Uploaders download includes two Mac tools to allow use of the until now Windows-only service. These include a plug-in for uploading images from within iPhoto and a standalone application for those who just want to upload occassional images.

The software was developed by search engine software engineer, Ted Bonkenburg. He built the software as a project during the 20 per cent of working time Google offers its staff to work on their own projects.

"For me this has been a great opportunity to meet and work with new people, explore new technologies, and help create something that I hope the Mac community will find useful," writes Bonkenburg on the official Google blog.
