Hi there,

This parameter was working when I was building on my local machine however when I uploaded it to Pavlovia then it stopped working. Images remain in native format. Code below. Please note Pavlovia seems to only have copies of jspsych-6.0.0 in its library - tried to use 6.1.0 and it would not run on their platform.

Disregard - was just some difference between 6.0 and 6.1.0.

Hi Cluster-Bomb,
I'm using 6.1.0 and I saw that Pavlovia only have 6.0 just as you said. I thought putting my jsPsych plugins folder in my project. Is it what you finally did? I saw a project like this on Pavlovia's Gitlab but I don't know if it works.
Thanks,
I.M.
