Why my fileServer handler doesn't work?

Question

I've a simple folder :

Test/
    main.go
    Images/
          image1.png
          image2.png
          index.html

In main main.go I just put :

package main

import (
       "net/http"
)

func main(){
     fs := http.FileServer(http.Dir("./Images"))
     http.Handle("/Images/*", fs)
     http.ListenAndServe(":3003", nil)
}

But when I curl on http://localhost:3003/Images/ or even I add to path file's name, it doesn't work. I don't understand because it's the same as the reply given on this subject

Can you tell me so that this does not work ?

You need to remove * and add extra sub-folder Images:
This works fine:

Test/
    main.go
    Images/
          Images/
                image1.png
                image2.png
                index.html

Code:

package main

import (
    "net/http"
)

func main() {
    fs := http.FileServer(http.Dir("./Images"))
    http.Handle("/Images/", fs)
    http.ListenAndServe(":3003", nil)
}

Then go run main.go

And:

http://localhost:3003/Images/

Or simply use:

package main

import (
    "net/http"
)

func main() {
    fs := http.FileServer(http.Dir("./Images"))
    http.Handle("/", fs)
    http.ListenAndServe(":3003", nil)
}

with: http://localhost:3003/
