Earlier this year, arising out of a conversation at GUADEC, I wrote a nautilus plugin to upload images to imgur.com. (This is useful because imgur doesn’t require an account: you can just install, hit "upload", and off you go.)
Here is a copy of the same thing as a MeeGo RPM, suitable for use on the Lenovo machines distributed at the MeeGo conference. Once this is installed, you can select a .jpg image in the file browser, press the menu button, and choose "Post to imgur" from the resulting menu. Equivalently, you can choose the same option from the Edit menu. The image will be uploaded, and the web browser will pop up at the new URL.
