Of course, all of these selections can be searched at one time. A larger version of the image appears when it is clicked on. The first of the two image-only search engines is Ditto , which is the first one I use when looking for pictures or clip art. The images can be viewed in detailed or compact format, and the number of images viewed per page can be selected. After an image is selected, two new windows will open, one with the image, and the other with the site from where the image was taken.
Ditto is a wonderful resource.
