The Swap Image behavior swaps one image for another by changing the src attribute of the ![]()
tag. Use this behavior to create button rollovers and other image effects (including swapping more than one image at a time). Inserting a rollover image automatically adds a Swap Image behavior to your page. Note: Because only the src attribute is affected by this behavior, you should swap in an image that has the same dimensions (height and width) as the original. Otherwise, the image you swap in shrinks or expands to fit the dimensions of the original image. There is also a Swap Image Restore behavior, which restores the last set of swapped images to their previous source files.
