Need help showing player on gui

Help and Feedback Scripting Support
#1 
local game = game:GetService("Players")
local ImageLabel = script.Parent

function setPlayerIcon(PlayerName)
	local Success, Err = pcall(function()
		local PlayerId = PlayerService:GetUserIdFromNameAsync(PlayerName)
		local ThumbType = Enum.ThumbnailType.HeadShot
		local ThumbSize = Enum.ThumbnailSize.Size180x180
		local Content, IsReady = PlayerService:GetUserThumbnailAsync(PlayerId, ThumbType, ThumbSize)
		ImageLabel.Image = Content
	end)
end

setPlayerIcon(game.Name)

So, my script doesn't show each player in the game's photo on the gui(Like a photo of the avatar)
I want it to show their picture for each player.

since you did

game = game:GetService("Players")

then you did

setPlayerIcon(game.Name)

aren’t you sending a variable for game.Players instead of Player Names?

#3

I am not sure how to get their names, do I make a table or something?

#4

yes

local players = game.Players:GetPlayers()

function setPlayerIcon(Players)
	local Success, Err = pcall(function()
for i,v in pairs(Players) do-- loops through all players till they are all registered
		local PlayerId = PlayerService:GetUserIdFromNameAsync(v.Name)--gets their name
		local ThumbType = Enum.ThumbnailType.HeadShot
		local ThumbSize = Enum.ThumbnailSize.Size180x180
		local Content, IsReady = PlayerService:GetUserThumbnailAsync(PlayerId, ThumbType, ThumbSize)
		ImageLabel.Image = Content
end
	end)
end

setPlayerIcon(players)
