Picasa
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. 🙁
Photo corruption – now there’s a topic! In fact, I will blog it myself.
