Hi, 

I need urgent help on an issue that I have with loading pictures in my experiment. The problem seems to be with coding that I've put in.

Screenshot #1 shows coding from my friends experiment and it works perfectly fine (it was coded for Windows version of Inquisit 4). It's the one where it shows: "C:Users/Maria/Desktop...

Screenshot #2 shows my incompetent way of coding and as a result of that I get s*** load of errors ^^.

I need guidance on how to code it correctly so that my Inquisit 5 on macOS knows where to look for specific pictures. As you can see I've tried it different ways and it shows errors anyways.
My question is, whether I have to code all of them correctly for the experiment to run properly, and if so, what would the right code be?

I need solution for this quite presto as it is crucial in my major thesis, so if anyone has an idea how to make it work I'd be enormously grateful ;)
