Displaying a random image with shake function

I'm currently having issues with my code. I'm a total newbie to this stuff so this may be an easy fix but I can't figure it out. I'm trying to have an random image load when the user shakes the iphone. I've managed to get the images to load up but I want the last image loaded to be replaced with the new image. It just keeps stacking the images on top of each other and I can't seem to remove the previous image on the shake function. Here's my code:

local shake = { "1.png", "2.png", "3.png", "4.png" }
 
function shake:accelerometer(e) if (e.isShake == true) then
        octohedron.isVisible = true
        transition.from(octohedron, {alpha = 0})
        local r = math.random ( 1, 4 )
    local imageResult = display.newImage( shake [r], 110, 176)
        transition.from(imageResult, {alpha = 0})
        end
end
        
Runtime:addEventListener("accelerometer", shake)

@reblewax,
this is how you grease the wheels on this code...

local shake={"...."}
local images={}
 
local i
for i = 1, #shake do
  images[i] = display.newImage(shake[i], 110, 176)
  images.isVisible = false
end
 
local function get_images(thisOne)
 local i
  for i=1,#images do
   images[i].isVisible = false
  end
  images[thisOne].isvisible = true
  return images[thisOne]
end
 
 
function shake:accelerometer(e)
  if (e.isShake == true) then
   octohedron.isVisible = true
   transistion.from(octohedron, {alpha=0})
   local r = math.random(1,4)
   local image = get_images[r]
   transition.from(imageResult,{alpha=0})
 end
end
 
Runtime:addEventListener("accelerometer", shake)

Thanks for the reply JayantV.

Can't seem to get it working :(

I'm using the director class from Ricardo Rauber for this app. Would that have any affect on this code? I'll post in the entire code here so you can see.

module(..., package.seeall)
 
new = function ()
        
        ------------------
        -- Groups
        ------------------
        
        local localGroup = display.newGroup()
        
        ------------------
        -- Display Objects
        ------------------
        local background = display.newImage("background.png")
        local octohedron = display.newImage("octohedron.png")
 
        ------------------
        -- Inserts
        ------------------
        localGroup:insert ( background )
        localGroup:insert ( octohedron )
 
        ------------------
        -- Positions
        ------------------
        octohedron.x = 160
        octohedron.y = 216
 
        octohedron.isVisible = false
 
 
local shake = { "1.png", "2.png", "3.png", "4.png" }
 
local images={}
 
local i
for i = 1, #shake do
  images[i] = display.newImage(shake[i], 110, 176)
  images.isVisible = false
  images.isVisible = false
end
 
local function get_images(thisOne)
 local i
  for i=1, #images do
   images[i].isVisible = false
  end
  images[thisOne].isvisible = true
  return images[thisOne]
end
 
 
function shake:accelerometer(e)
  if (e.isShake == true) then
   octohedron.isVisible = true
   transition.from(octohedron, {alpha = 0})
   local r = math.random(1,4)
   local image = get_images[r]
   transition.from(imageResult,{alpha=0})
 end
end
 
Runtime:addEventListener("accelerometer", shake)
 
        ------------------
        -- MUST return a display.newGroup()
        ------------------
        
        return localGroup
        
end

I noticed on line 39 and 40, you have images.isVisible = false -- try changing it to images[i].isVisible = false (and to tidy it up, remove the duplicate from line 40)

Ah! Good catch. Still no go on the code though:(
