Picasa for Linux!
There is one single tool that rules the world for photo management. This tool is called Picasa. Up until now, it was only available for Windows, which sucked bigtime and I definitely liked the app. Big Google rules (again!). They created a linux version!
OK, not really. They made an installer that includes a specially configured Wine to run Picasa on Linux. But it functions just like a native Linux app!
So go and download your Picasa for linux :)
