Cloud photos for presentations and documents

I've been working on a talk I'm giving at Cloud Computing Congress in China and (I'm not ashamed to admit) I spent a lot of time looking for just the right cloud photo. I thought I'd share the best photo's I came across, in case you ever need to give a talk about The Cloud (or just love photo's of clouds).

Note: These photos are all be licensed under Creative Commons, and came from a combination of Flickr Creative Commons search and Google Images (manually excluding non-Creative Commons images).

The photos are divided into four sections:

1. Simple clouds


2. Dark clouds


3. Powerful clouds


4. Unique clouds

Simple clouds

Dark clouds

Powerful clouds

Unique clouds

You can find all of these cloud photos here. If you have other favorites and are willing to share, please add a link to them in the comments.
