Perhaps you should try some spelling variations:
stereo images » stereo image
steps images » stego images, stele images, stem images
steel images » stego images, steel wages, stele images
stego image » stego images, stereo image

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: 10 ((((steps images) OR (steel images))) OR (((stego image) OR (stereo images)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "10 ((((steps images) or (steel images))) or (((stego image) OR (stereo images))))".
• Adding a wildcard symbol may retrieve word variants: 10 ((((steps images) or (steel images))) or (((stego image) OR (stereo images))))*.
