no no, I mean you can go to Google, type in dolphin images, and it will give you a list of images on the web. Pretty useful. Then you can just copy the picture into a file, modify it with Paint, Image Forge, or a similar program (I miss my Image Forge), and you'll be all set. All of the prehistoric animals I presented in the Suggestions for New Cave Units thread were done in this way.

It works quite well for many subjects.

A similar trick is to find a picture of a miniature and copy that, then modify the picture like you would any other, in a graphics program.

Thirdly, their are literally thousands of free pixel images (sprites) in the Web, usually pretty high quality. Again, I wouldn't use even the free ones without modifying them somewhat, but they are available.
