How do I use instance variables to load different images

Hi,

I am trying to load a different image from url for each instance of a sprite on layout start. I have set the different urls up as instance variables of a sprite object and tried using the 'for each' loop to set them on layout start, and following reading this tutorial just setting them without a loop.But both times all instances have the same image.

I am building a simple "I Spy" game for my daughter and plan is that the instances will represent a different word that can be selected to match the target letter and they will be randomly loaded each play.

Any help will be greatly appreciated!
