+ * `files` (uniform filenamearray): an array of URI of image files.
+ * `index` (integer): the index of the image to use from the array of images provided. If the value for `index` is outside the range of the provided image filenames, then the behavior is undefined.
+ * `default` (float or colorN or vectorN): a default value to use if the indexed filename from `files` can not be resolved (e.g. if the resolved file URI cannot be read). The `default` value must be the same type as the `` element itself. If `default` is not defined, the default color value will be 0.0 in all channels.
