I do not see an ImageIcon call on line 74:

https://github.com/ad1054/Postcards/blob/master/src/main/java/PostCard.java#L74

This suggests that your repository is desynchronized with your local code.

In any case, it looks as if the getClass().getResource("/English.jpg")
call returns null. So the best idea would be to add a debug statement
(i.e. a System.err.println()) to show what
getClass().getResource("/PostCard.class") returns; You can then deduce
where the English.jpg is expected to be (but cannot be found).

Ciao,
Johannes
