Completely free images to use in your website

I am always looking for photo archives where you can get images free of rights, so I can use them in my apps as dummy images.

This is a good place to start: http://www.morguefile.com/archive

Other alternatives that you may find useful is to search for images in Flickr that can be used under Creative Commons License:

The above link will help you find those CC licensed images.

Enjoy!
