How do I make my pet hatching script display an image of the pet I got? (instead of text)

here is my script and i wanna remove the text and only have it display an image of the pet i got.

local plr = game.Players.LocalPlayer
local open = plr:WaitForChild('OpenValue')
while wait(0.1) do
if open.Value == "Open" then
	wait(.2)
	script.Parent.Visible = true
	wait(.2)
	script.Parent.Rotation  = 3
	script.tic:Play()
	wait(.2)
	script.Parent.Rotation  = -3
	script.tic:Play()
	wait(.2)
	script.Parent.Rotation  = 3
	script.tic:Play()
	wait(.2)
	script.Parent.Rotation  = -3
	script.tic:Play()
	wait(.2)
		script.Parent.Rotation  = 4
	script.tic:Play()
	wait(.2)
	script.Parent.Rotation  = -4
	script.tic:Play()
	wait(.2)
	script.Parent.Rotation  = 5
	script.tic:Play()
	wait(.2)
	script.Parent.Rotation  = -5
	script.tic:Play()
	wait(.2)
		wait(.2)
	script.Parent.Rotation  = 6
	script.tic:Play()
	wait(.2)
	script.Parent.Rotation  = -6
	script.tic:Play()
	wait(.2)
	script.Parent.Rotation = 1
	script.Open:Play()
	wait(.1)
	script.Parent.Visible = false
	wait(.1)
	script.Parent.Parent.Pet.Visible = true
	script.Parent.Parent.Pet.Text = "You got "..plr.GotPet.Value.." !"
	wait(2)
	script.Parent.Parent.Pet.Visible = false
end
end

Edit: If this is what you mean by where plr.gotpet is stored then its in my leaderstats:

                                                                                                                                                          game.StarterGui.ResetPlayerGuiOnSpawn = false
local DataStoreService = game:GetService("DataStoreService")

local playerData = DataStoreService:GetDataStore("PlayerData")

game.Players.PlayerAdded:connect(function(Player)
	local leaderstats = Instance.new("Folder", Player)
	leaderstats.Name = "leaderstats"

	local val1 = Instance.new("StringValue",Player)
	val1.Name = 'GotPet'
	val1.Value = ''

	local val2 = Instance.new("StringValue",Player)
	val2.Name = 'OpenValue'
	val2.Value = ''

	local Gems = Instance.new("IntValue", leaderstats)
	Gems.Name = "Gems"
	Gems.Value = 0

	local Rebirths = Instance.new("IntValue", leaderstats)
	Rebirths.Name = "Rebirths"
	Rebirths.Value = 0

	local Coins = Instance.new("IntValue", leaderstats)
	Coins.Name = "Coins"
	Coins.Value = 0

	local playerUserId = "Player_" .. Player.UserId  --Gets player ID

	local Success, Result = pcall(function()
		return playerData:GetAsync(playerUserId)
	end)

	if Result then
		print("Data found!")

		Coins.Value = Result[1] -- // Since in the saving part, Coins are the one that is set as the first value of the table, we set Coins as [1]
		Rebirths.Value = Result[2]
		Gems.Value = Result[3]
	else
		print("DataStore working but No data found")
		warn(Result)
	end

end)

local function onPlayerExit(player)  --Runs when players exit



	local success, Err = pcall(function()
		print("Data Saved successfully")

		local playerUserId = "Player_" .. player.UserId

		playerData:SetAsync(playerUserId, {player.leaderstats.Coins.Value, player.leaderstats.Rebirths.Value, player.leaderstats.Gems.Value}) -- Now set as a table instead of individually

	end)



	if not success then
		warn(Err)
		warn('Could not save data!')
	end
end

game.Players.PlayerRemoving:Connect(onPlayerExit)

and here is where the pet is chosen

local userInputService = game:GetService("UserInputService")
local RS = game:GetService("ReplicatedStorage")
local Eggs = require(RS:WaitForChild("Eggs"))
local Data = Eggs[script.Name]
local Cost = Data["Cost"]
local Pets = Data["Pets"]


local Buy = game.Workspace.Eggs.Common
local Cost1 = Buy:WaitForChild("Cost")
local CD = Buy.Buy.Select:WaitForChild("ImageButton")
local CostGUI = Cost1:WaitForChild("Am")
local CostText = CostGUI:WaitForChild("TextLabel")

CostText.Text = Cost.." Coins"

local TotalWeight = 0
for i,v in pairs(Pets) do
	TotalWeight = TotalWeight + v[1]
end

local function ChoosePet()
	local Chance = math.random(1,TotalWeight)
	local Counter = 0
	for i,v in pairs(Pets) do
		Counter = Counter+v[1]
		if Chance <= Counter then
			return i
		end
	end
end

CD.Triggered:Connect(function(Player)
	local Stats = Player:WaitForChild("leaderstats")
	local Coins = Stats:WaitForChild("Coins")
	local open = Player:WaitForChild('OpenValue')
	local got = Player:WaitForChild('GotPet')
	if Coins.Value >= Cost then
		Coins.Value = Coins.Value - Cost
	open.Value = 'Open'
	got.Value = ChoosePet()
	local findpet = Player:WaitForChild('Pets')
	local sqq = findpet:FindFirstChild(got.Value)
     sqq.Value = 'owned'
		wait(5)
	open.Value = 'Close'
	got.Value = ''
	end
end) -- // this code has an error on CD.Triggered i know. but im fixing that soon.

I dont have the images store anywhere currently as i dont know exactly where to store them.

You'll have to be more specific on where you get the images of pets. Are they saved somewhere in your game? Are they uploaded as decals? Where do you store the decal IDs?

In terms of your code though, there are many improvements you can make. The big one is using a loop instead of pasting (close to) the same code every time. Try something like this:

local plr = game.Players.LocalPlayer
local open = plr:WaitForChild('OpenValue')
while true do
    if open.Value == "Open" then
        script.Parent.Visible = true
        for i = 3, 6 do
            script.Parent.Rotation = i
            script.tic:Play()
            wait(0.2)
            script.Parent.Rotation = i * -1
            script.tic:Play()
            wait(0.2)
        end
        script.Parent.Rotation = 1
        script.Open:Play()
        wait(.1)
        script.Parent.Visible = false
        wait(.1)
        script.Parent.Parent.Pet.Visible = true
        script.Parent.Parent.Pet.Text = "You got "..plr.GotPet.Value.." !" -- You can add a line of code after this to set a pet image but you would need to share how GotPet is set.
        wait(2)
        script.Parent.Parent.Pet.Visible = false
    end
    wait(0.1)
end

This will loop from 3 to 6, set the rotation to 3, then -3, then 4, then -4, then 5, and so on. Just like your code did, only this is a bit cleaner.

You'll have to provide some more info about the image data since you need to have them somewhere in order to load them (decal IDs).

You could just use ViewportFrames, and locate the camera infront of a position where you can place the pet?-

Not that hard, to be honest, you don't even need much code for it, unless you count

local a : ViewportFrame = ...

a.Visible = false

if (...) then
   a.Visible = true
   wait(...)
   a.Visible = false
end
