What is your preferred image viewer?

[baz]

Hello, I am wondering what image viewers people are using? I am looking for something ridiculously light, not a photo organizer or anything, and definitely not the awesome gimp. Currently I am using FL-PicSee and its quite good, easy to use, fast - what are the rest of you using?

gqview is in the repo.

I've been using gqview almost exclusively for years. I have issue with its lack of speed, particularly in directories of several hundred+ images, but otherwise it's the best I've seen.  Its bulk renaming and the remembering of move/copy directories have been handy many times.
