+     * message, asking you to be honest when using the
+     * software. I ask you the same, if your intention is to
+     * use ImageKit. Writing this plugin took a lot of time
+     * and it hopefully saves you a lot of headaches. If you
+     * would use a cloud-provider instead of rolling your own
+     * thumb engine, then your would also have to pay them.
+     *
+     * Anyway, have a nice day!
