First time actually using rainmeter instead of trying to find the right skins to go together. I don't understand how to do anything with hovering.

So I made a pokemon background and added pokemon sprites as shortcuts to different things, like so.

What I would like to do is have the pokemon change to the "shiney" or off colored version of the sprite when I hover over it. The problem is I don't know what I'm doing.

My .ini files look like this:

[Rainmeter]
Update=1000

[Variables]
Folder1="C:\Users\[MY NAME]\AppData\Local\Google\Chrome\Application\chrome.exe"

[MeterFolder]
Meter=Image
ImageName=arcanine.png
LeftMouseUpAction=!Execute ["#Folder1#"]

I just copy/pasted from a forum post and changed the details to do what I want. I don't know if I can add hover effects to that, mainly because I can't understand the things that google leads me to.

Anyone willing to help?
