Just because an image is available for download on the web, it doesn't necessarily mean you can use it.
Images, including photographs, illustrations or diagrams from books, journals or the web are subject to copyright in their own right. Be aware that there can very often be more than one set of rights in an image, for example, a photograph taken in 1999 of a painting by Van Gogh – the painting is clearly out of copyright but the photograph is still protected.
Copyright in artistic works lasts until 70 years after the death of the artist/photographer. However, there may be other legal protection preventing you from using the work e.g. a cartoon character may be registered as a trademark.
So beware Google images for example, this is merely a search engine which finds images from different websites all over the Internet. It is usually not possible to re-use such images without obtaining the permission of the copyright holders of the particular material in question.
