This template is used to display a stereogram or autostereogram, first as separate frames (by displaying exactly one half of one image), then as one continuous image formatted for paralleled and/or cross-eyed viewing (accomplished by switching the relative position of each half).
Parameters include "image", "caption", "width", "height", and "swap".
{{stereo image
|image = PSM V21 D047 Left and right projection of a cone.jpg
|caption = caption
|width = 320
|height = 145
|swap = <!-- set this if source image is cross-view, otherwise parallel is assumed -->
}}
