Displaying Random Images
So, when the user clicks, it makes another frame visible making itself invisible while at the same time display 4 random images. I have 1 image so far (I will be making the others later): images/http://www.roblox.com/asset/?id=146289136 I have got as far as this:
local PackPlayers = {"Nytroz", "Legendowski", "HypervenomPhantomz"}
numOfPlayers = 4
numOfPlayers meaning the maximum amount of images to display. Am I going about this correctly? And how would I continue? My previous code was this:
local PackPlayers = {"Nytroz", "Legendowski", "HypervenomPhantomz"}
numOfPlayers = 4
for i=1,numOfPlayers do
PackPlayers[i] = display.newImageRect("images/http://www.roblox.com/asset/?id=146289136", 200, 280)
PackPlayers[i].x = math.random(0, display.contentWidth)
PackPlayers[i].y = math.random(0, display.contentHeight)
end
I found it on the internet and tried to edit the syntax to work with Roblox LUA. But of course it didn't work. So I am asking you guys here to assist me.

For starters, you are trying to use members of display. If this is all your code, display is nil, meaning it will error.
I also don't understand your code. Why are you overwriting PackPlayers?
If you just want to show random images, why would you need ImageRects? Why not show the Images themselves?
I would do this:
local PossibleImages = {146289136}
local MaxImages = 4
function GetImage()
return "http://www.roblox.com/asset/?id="..PossibleImages[math.random(1, #PossibleImages)]
end
function CreateImage(img, x)
local new = Instance.new("ImageLabel")
new.Image = img
new.Position = UDim2.new(0.2 * x, 0, 0.5, 0)
new.Size = UDim2.new(0.1, 0, 0.1, 0)
new.Parent = game.Players.LocalPlayer.PlayerGui.Gui -- somewhere in PlayerGui
end
button.MouseButton1Down:connect(function()
button.Visible = false
for i = 1, MaxImages do
local img = GetImage()
CreateImage(img, i)
end
end)

Well, uh, display.newImageRect isn't even part of the ROBLOX API.
What I think you want to do is make a image on the screen. In this case, you'll want to use a ImageLabel.
Also, you're going to need to use a TextButton or ImageButton to detect those clicks.
To create an ImageLabel, just follow the standard procedure when creating objects in the ROBLOX API:
local image = Instance.new("ImageLabel")
image.Parent = script.Parent
image.Size = UDim2.new(0, 300, 0, 300)
image.Image = "rbxassetid://1234"
image.Position = UDim2.new(0, 300, 0, 400)
-- and so on
