If that’s your goal you have to mess around with camera cframe and create a function that updates your viewport frame everytime you make a camera rotation

local players = game:GetService("Players")
local runService = game:GetService("RunService")
local currentCam = workspace.CurrentCamera

local mainPart = workspace:WaitForChild("GOOBER")
local attachment = mainPart:WaitForChild("img_Att")
local billboard = attachment:FindFirstChildWhichIsA("BillboardGui")
local imageLabel = billboard:WaitForChild("img")

local rotations = {0, 45, 90, 135, 180, 225, 270, 315}
local images = {
    [0] = "rbxassetid://11104447788",
    [45] = "rbxassetid://12936162825",
    [90] = "rbxassetid://12236696313",
    [135] = "rbxassetid://13370612666",
    [180] = "rbxassetid://16014360744",
    [225] = "rbxassetid://7266774615",
    [270] = "rbxassetid://10047977817",
    [315] = "rbxassetid://1380194908"
}

local function normalize(angle)
    angle = angle % 360
    return angle < 0 and angle + 360 or angle
end

local function getClosestRotation(angle)
    local closestRotation
    local minDifference = math.huge
    for _, rotation in ipairs(rotations) do
        local difference = math.abs(normalize(rotation) - angle)
        if difference < minDifference then
            minDifference = difference
            closestRotation = rotation
        end
    end
    return closestRotation
end

runService.RenderStepped:Connect(function()
    local camRight = currentCam.CFrame.RightVector
    local mainPartOrientation = -(mainPart.CFrame.RightVector)

    local angle = math.deg(math.acos(camRight:Dot(mainPartOrientation)))
    if camRight:Cross(mainPartOrientation).Y < 0 then
        angle = 360 - angle
    end

    angle = normalize(angle)
    local closestRotation = getClosestRotation(angle)

    imageLabel.Image = images[closestRotation]
end)
