I'm not familair with picture/art code if their syntaxes have been changed, but there's been a few changes in the syntax of some other scripts/code lines (from 5.3 to 5.4), as can be seen here:
http://docs.textadventures.co.uk/quest/ ... notes.html (scroll down to 'upgrading quest from 5.3 to 5.4' category/section)
so, you just need to convert your old syntaxes of these over to the new syntaxes of these
and you need to change this code line (at the very top of your entire game code):
<asl version="530">
to:
<asl version="550">
~ or (it depends on what version of 'quest.exe' he/she downloaded) ~
<asl version="540">
