How do you show a local player profile picture on an ImageLabel?

Hi, I'm trying to make a horror game and I want a television to show the local player's image. I have tried several blocks of code to make this happen, but the image is always transparent. I am aware of the fact that the following code blocks are messy and unorganized, but I was in a rush to complete them. These codes include: 1:

-- this one was in a block that starts the television change when touched. I cut out a lot of the
--initial code to shorten it. It's in a default script.
local debounce = false
script.Parent.Touched:Connect(function(hit)
if hit.Parent:FindFirstChild('Humanoid') then
if not debounce then
debounce = true
local hi = game.Players[hit.parent.Name]
game.Workspace.Telly.Screen.Image.ImageLabel="http://www.roblox.com/Thumbs/Avatar.ashx?x=100&y=100&Format=Png&username="..hi

2:

--this one I put inside the television itself's screen. I tried it with and without being inside a
--normal and a local script.
local player = game.Players.LocalPlayer.Name

function update()

script.Parent.Image= "http://www.roblox.com/Thumbs/Avatar.ashx?x=100&y=100&Format=Png&username="..player

end

update()

3:

--this one is the same as the above, but using the UserId instead of the username. It still
--doesn't work. Once again, tried local and default scripts.
local player = game.Players.LocalPlayer.UserId

function update()

script.Parent.Image= "https://web.roblox.com/Thumbs/Avatar.ashx?x=100&y=100&Format=Png&userid="..player

end

update()

--at this point, i had run out of ideas. This was my last-ditch effort attempt.
script.Parent.Image= "https://web.roblox.com/Thumbs/Avatar.ashx?x=100&y=100&Format=Png&userid="..game.Players.LocalPlayer.UserId

I don't what's wrong with these scripts. Please help me fix it.
