Using python and OpenCV, is it possible to display the same image on multiple users? Or choose a user to display the image?

I am using cv2.imshow but it only displays the image for the user that runs the script.

not with opencv's builtin highgui functions.

maybe you can setup some (web)server, to stream it to multiple users, but that's pretty much off-topic.

Thanks for your reply. Sorry I didn't explain myself properly, the user I want to display the image on is within the same computer. I am able to save photos in their directory so I thought there might be an easier way of displaying an image too. (sorry I'm quite a novice in this and a non native speaker :) )

I found a way of doing it, not related to OpenCV though. I was able to display the images on another user/host by setting the DISPLAY environment variable of the X server to match the desired user's DISPLAY.
