As Rick said, declare the variables in the general declarations area i.e. at 
the top of the coding, and not inside any procedures. If you called the 2 
variables n1 and n2 then you can use that later i.e. instead of having 
image(index).tag you would have image(n1).tag and image(n2).tag. Hopefully 
this is making sense to you.
