 ### Show command
 
-zIndex controls whether the image will be displayed over or under another image. Images with higher zIndex values are drawn over the top of images with lower zIndex values. Opacity controls whether to display the image as solid or semi-transparent. Opacity values range from 1-100, with higher opacity values making the image less transparent. The default is 100 resulting in a solid image.
