 * @param bool $src_only         Url to the image only(true) or an image tag (false)
 *
 * @param bool $randomize_sizes  Try to avoid repeating the same image by slightly varying the size, creating a
 *                               different seed? Useful if using something like object-fit. Less so if you need extra

 *
 * @param int  $random_deviation How much can the size vary? (only applicable if $randomize_sizes is true
 *
 * @return string

 *  Uses:
 *  iso_random_unsplash( 500, 500 );
 *  <img src="<?php echo iso_random_unsplash( 250, 300, true); ?>">
