Ah, sorry, I forgot you are using an instance of the original Ibex farm, not a standalone version of the experiment. The original Ibex farm doesn’t readily come with hosting solutions for multimedia resources (which is a feature we added to the PCIbex Farm when we set it up)
If you want to host any multimedia file on the farm, you will need to upload them to the www subfolder of your project’s folder on the farm’s server. This should be easy if you are the one who set up the farm, otherwise you’ll have to contact whoever is in charge
