+  - Change within the **v-for** the **x** to **z**.
+  - Execute your script  --> The images will will disappear. Why?
+  - Then change **x** within the //<figcaption>// and the //<img>// from **x** to a **z** as well --> The images will appear again. Why?
+  - Note down for what the first respectively the second usage of **x/z** stands for.
