• border: Grey border line around the image rim to distinguish from the pale backgorund if necessary. Any input will activate the border. Empty entry for no border by default.
• collapse: enabling the [show/hide] button to toggle the display of overlap layer.
• base: File name of the base (bottom) image
• base_style: Additional CSS code
• base_width: Width to display the base image, in pixels
• base_alt: alt attribute for the base image, text for visually impaired readers; see WP:ALT for properly written alt text
• base_caption: Title attribute for the base image, served as the pop-up tooltip message when mouse lays over it.
  • The pop-up message will display the alt text instead of title text in IE7 and older versions. This interpretation is now considered incorrect.
• base_link: Linking for the base image
• float: File name of the 1st layer image
• float_width: Width to display the 1st layer image, in pixels
• float_alt: alt attribute for the 1st layer image
• float_caption: Title attribute for the 1st layer image, served as the pop-up tooltip message when mouse lays over it.
• x: Distance to offset the 1st layer image from the left edge of the base image, in pixels or any other CSS-standard units
• y: Distance to offset the 1st layer image from the top edge of the base image, in pixels or any other CSS-standard units
• t: Text for the 1st layer
  • If the text exceeding the border of the base dimension is undesirable, use another layer specifically for the text only.
• link: Linking for the 1st layer image
  • When applying the 2nd-50th layer, add the number after all of the words float, x, y, t and link of floating image-related parameters to indicate their layer order as shown in the example. The image of the greater number will always appears over the smaller number layer.

• Superimpose2 has the downward compactibility with the original ((Superimpose)), if the later does not exist in your working Wiki, you can ignore the original and transwiki this version only. Preferably making a WP:redirect.
• Remember to copy ((Superimpose2/base)) as well during transwiki.

• ((Annotated image)), allows text notes to overlap image, allows cropping
• ((Superimpose)), supports simpler layer superimposition.
• ((Location map)), places a single image over another at a map coordinate location
• ((Lageplan)), related template to Location map with specific features
