What image software does /c/ use? I've been a fairly loyal ACDSee user for a while, but I'm looking for a replacement. I liked ACDSee because of its incredibly fast image processing so I could scroll through a collection rather quickly with my mouse, and I haven't seen any other application that does the same. Most I've seen that I can recall have a zoom feature attached to the mouse wheel.

I'd personally like a program that also easily manages metadata tags so I can categorize my images.

So I ask how does /c/ like to browse their image collection? Do you use anything besides the built-in image viewers for your respective OS?

Here's a random Horo image.
