Irfanview nearest equivalent for linux

I heart IrfanView. Although for Gnome, I use gthumb as my Linux equivalent. It doesn't have the myriad of swiss-tools that IV has, but quality scaling, cropping and color adjustment suits me well enough. I do love how gthumb imports photos from my camera :D

As a Kubuntu user, I've stuck with the default image viewer for KDE - Gwenview. It's sufficient for everyday operations and I believe you can even extend it with plugins.

And yes, GIMP goes without saying, although it might be too bloated for quick edits. ;)

Personally, I think Picasa from Google is pretty good, although it is not open source.
