 * Hey mate,
 * Thanks for the plugin,
 * There is one PHP Warning that occurred to me – this can be usually easily fixed
   with something like if isset() etc..
 * Notice Undefined index: cb 1 wp-content/plugins/categories-images/categories-
   images.php:230
 * I would recommend using Query Monitor plugin while developing plugins – super
   helpful!
 * Hope that helps,
 * Lukas
