Let images move
I am working on an experiment and the idea is that the participants will see three pictures in a row (horizontal): In some trials the first picture has to move upwards and the second and third picture downwards. In other trials the first and second picture have to move upwards and only the third picture downwards (difference in speed will be great too). Or even more complicated, the first pictures jumps over the second and third picture and the second and third picture have to move a little to the left. I was wondering whether this is even possible by just using a script for example, and if so, how to do this?
If not, suggestions are more than welcome! I have thought about making short movies with powerpoint and upload these, but because we will have between 210 and 300 items I am afraid we will get memory issues.
