Some pictures are not displayed

URL of experiment: face_memory3 [PsychoPy]

Description of the problem:

Hi everyone,

I created this online experiment with builder, which adds code component.

There were no problems when I tested the experiment, but almost half of the participants (IP addresses in China) had problems with the experimental pictures not showing up during the img_show rountine.

If you need additional infos, just let me know.

Thanks a lot!

Hi Dinny,

Was it any particular subset of images that did not show? (e.g. did they share some commonality in file size or type? compared with pictures that were shown?)


Hi Becca,

Thank you very much for your reply!

The images that don’t show are all from the same folder “image3”, but they are the same size and type as the images in the other folders of this experiment.

Do you know of any possible reasons?

Thanks in advance.



Also, the issue only occurs if participants use a Chinese IP address.
