I just downloaded Picasa for Linux from Google Labs. It’s a really nice tool for organising all the pictures on your harddisk, and it gives you nice tools to improve photo quality. It is also integrated with Blogger, so I posted this from within Picasa.
Update: In posting this, I seem to have unearthed a bug in the software. I swear the photo looked fine on my harddisk, but somehow Picasa corrupted the bottom half while uploading it.
