Because you're using a place as an asset id... Sometimes you need to subtract two to get the proper image id. Edit... And I am not seeing how you're not getting the image. Go to Roblox Studio, open the Toolbox, click your image, paste it on a brick or something, copy the ImageId off that.
Thanks ;)
