No they were not, I did not know that, now I do not get the error message anymore thx.
 
 The problem now however is that it does not seem to match any poster to the entries.
 
 I have exported the ID from my old database so they should match the ID's in the image folder, right?
 Unless the ID's have changed during the re-import into my new database? Where can I find the ID of a movie in the database?
 NOTE: The image files are named as follow:  MOVIE NAME_ID.jpg
