The "then" is superfluous, so its removal shouldn't affect anything. A 
"then" can only occur at the end of a line that begins with "if". The 
engine must be ignoring the extra "then" because it isn't throwing an 
error. At any rate, you don't need it.

Previously I believe you had the image in a background group with "act 
like a background" turned on, which means the same image will appear on 
every card that contains that background. I think you've changed that 
now by turning off "act like a background" or by moving the image out of 
the group. That is why only one card updates now.

The reason you need to leave the card and return in order to see the new 
image content is because you have placed the command in an openCard 
handler, which only triggers when you arrive at the card. Leaving and 
returning to the card will cause an openCard message to be sent, which 
updates the image content.
