/**
 * A function that takes an {@link module:ol/Image~Image} for the image and a
 * {string} for the src as arguments. It is supposed to make it so the
 * underlying image {@link module:ol/Image~Image#getImage} is assigned the
 * content specified by the src. If not specified, the default is
 * <code>function(image, src) {
 *   image.getImage().src = src;
 * }</code>Providing a custom imageLoadFunction can be useful to load images with
 * post requests or - in general - through XHR requests, where the src of the
 * image element would be set to a data URI when the content is loaded.
