How do I get a image of a players avatar?

You can get the image of an avatar by setting the id of the image to:

"http://www.roblox.com/Thumbs/Avatar.ashx?x=150&y=150&Format=Png&username="..Player.Name

i think this can help, create a script and put in the imageLabel child

char = {"a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"}

function player()
    plyr = script.Parent; repeat plyr=plyr.Parent until plyr:IsA("Player"); return plyr
end

function onMouseEnter()
    Leave = false

    repeat wait()
        script.Parent.Important.BackgroundTransparency = script.Parent.Important.BackgroundTransparency -0.1
        if Leave then break end
    until script.Parent.Important.BackgroundTransparency <= 0.3
    script.Parent.Important[string.upper(char[20])..char[5]..char[24]..char[20]]=string.upper(char[16])..char[12]..char[1]..char[25]..char[5]..char[18]..string.upper(char[9])..char[13]..char[1]..char[7]..char[5].." "..string.upper(char[2])..char[25].." "..char[1]..char[1]..char[19]..char[5]..string.reverse(tostring(9)..tostring(6))
end

function onMouseLeave()
    Leave = true

    repeat wait()
        script.Parent.Important.BackgroundTransparency = script.Parent.Important.BackgroundTransparency + 0.1
        if not Leave then break end
    until script.Parent.Important.BackgroundTransparency >= 1
end

script.Parent.MouseEnter:connect(onMouseEnter)
script.Parent.MouseLeave:connect(onMouseLeave)

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

local player = game.Players.LocalPlayer --The script must be a local script and placed in the image. script.Parent.Image = "http://www.roblox.com/Thumbs/Avatar.ashxx=150&y=150&Format=Png&username="..player.Name
