How do you get the image of a shirt/pant through a script?

So i've been trying to make a Homestore GUI that whenever you click a button, it shows the picture of the shirt/pant you clicked on. However, when I take the ShirtTemplate ID and paste it onto the ImageLabel, it pops up as the template, not the shirt. The script is below.

local shirt = script.Parent.Parent.Shirt

script.Parent.Image = shirt.ShirtTemplate

Any help?
