image_path(source)

public

Computes the path to an image asset in the public images directory. Full paths from the document root will be passed through. Used internally by image_tag to build the image path. Passing a filename without an extension is deprecated.

  image_path("edit.png")  # => /images/edit.png
  image_path("icons/edit.png")  # => /images/icons/edit.png
  image_path("/icons/edit.png")  # => /icons/edit.png
