"It's not a fully featured image processing suite like GIMP, but for 99% of common daily tasks that the average user might undertake, from rotating, resizing, cropping, and exporting images to online albums, GwenView is ideal.
"GwenView is a KDE4 application, but it will run on Gnome desktops as well. I had it installed on my new laptop running Ubuntu without any problems.
"GwenView opens into a file explorer style main interface, with the hierarchy of the home directory listed. From there, click on any category and dig deeper, with a stylish transition into the sub-directories, similar to what you get on Moblin."
