Images not loading properly, returning error message

I think you need to avoid using the html folder with the latest version of PsychoPy

Practice file (xlsx) cannot be found

If I were you I would start again in a fresh folder with the output path set to blank (not html). Nothing is needed in the completed URL field but you are confusing PsychoPy by using the historical html/resources method and the modern attached resources.
