If you are looking on Google for clipart then you might want to use a Google advanced image search to find the kind of clip art that you are looking for – especially if you want to find a particular image, say of a dog or something, then you can go to the Google advanced image search and you can select the option ‘clip art’ rather than a photo or a drawing or the straightforward search will will bring up all images whether clip art or not.
