Let's break it down. |Image = <--- This is the image parameter of the infobox Now normally, you'd have Image=File:NAMEOFFILE.png, but we want to switch between images; this is where comes in.  <--- This is the switch operator. It allows you to switch between a set amount of items (in this case, four) In order to define those four items, we use |#=, where # is a number. |0=Creator1 <--- This is the first item |1=Creator2 <--- This is the second item etc., etc. }}Stage.png <--- This closes the operator and defines anything the files should have in common (be in that they all end in Stage.png, for example). What this whole thing does is alternate between File:Creator1Stage.png, File:Creator2Stage.png, File:Creator3Stage.png and File:Creator4Stage.png.
 * Image=File:Stage.png

So what does {{#expr: {{#time: i|now}} do? {{#expr: {{#time: i|now}} <--- This defines when to switch the images. It would be every time you refresh the page, but Wikia's cache is terrible.
