### B.2.1 BasicImageDisplay

Functions for display of graphics-format images in a no-frills viewing window (an `ImageWindow`). Supported image formats include GIF, JPEG, PNG and FITS, which may be compressed.

`displayBasicImage( label, loc )`
  Displays the file at a given location as an image in a graphical viewer. `label` may be any string which identifies the window for display, so that multiple images may be displayed in different windows without getting in each others' way. `loc` should be a filename or URL, pointing to an image in a format that this viewer understands.

  - Parameters:
    - `label` (String): identifies the window in which the image will be displayed
    - `loc` (String): image location
  - Return value
    - (String): short log message
