  • border: Grey border line around the image rim to distinguish from the pale background 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
  • y: Distance to offset the 1st layer image from the top edge of the base image, in pixels
  • 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
  • {{Overlay}}, allows multiple annotations to be place over an image with a legend
