Template:HoverImage/doc

Documentation
This template displays a default image, then substitutes another image when the reader hovers over it (e.g. if visual users place their mouse over the image). It is primarily intended for showing an undoctored image to the casual reader, but highlighting certain aspects on close inspection.

Bear in mind that the casual reader may not hover over the image, so will not see the intended effect. In addition, it may be difficult to follow links to the default image, as this will change on hovering. For this reason the images should be similar to each other (see examples below).

Usage
The template is intended to mimic the wikitext convention for images. The first two parameters are the names of the default and hover-revealed images respectively. All other parameters are the same as for images, and are applied simultaneously to both images, apart from the caption. If there is more than one potential caption, then the first caption is used for the default image and the last for the replacement image.
