image not refreshed correctly

[williamwongys]

I passed updated image from custom action to chatroom, but every time the same image is being displayed instead of the new image. I have checked the png file, it is the latest. I suspect chatroom caches the image instead of retrieving from the disk again. Is there any way I could force retrieval of the image again?

I don't think we cache anything. Have you ruled out and browser caches? Or server-side caches.
