Hi Dave,
are you really sure this works? It would mean that Inquisit parses an item at startup, tests for each element whether it refers to an existing file, and if so, tries to load this file as a picture.
I've put together a sample experiment and attached it (don't bother about the picture selection, it's just for example purposes). The script won't compile because the <%values.currentpic%> isn't parsed as a variable but taken for a file name.
Did you really get something like this to work?
Malte.
