When I was looking for lifestream pictures to use for my own website, I never found any that weren't covered with text or other images. So I made my own.

Then I say a post over at the Lifestream Forum where someone was also looking for lifestream images.

Seeing as there seem to be more people looking for that kind of image, I went and put together a set of lifestream stock images that you can download from my DeviantArt account. There are over 50 images in the zip file that you can mix and match to make your own lifestream image. :)
