Google Advanced Image Search
Did you even know there was an advanced image search option?
Well if you didn’t then this may be handy for future use.
Simply go to http://www.google.com/advanced_image_search and there you have far more options to refine your search for images on the web. One of the most useful options is to filter images by licence type, for those wanting to find images available on the web which are not subject to copyright, simply choose one of the free for commercial use options under ‘usage rights’. This can be useful perhaps if you are designing your own website..
