Website image CDN cache. How long will it be updated after a new image is uploaded?

The general practice is to add a version number at the end of the file when you update a static file to make CDN take effect immediately.
For example: bugall. js ----> bugall. js? Time = 1402394823

Bugall.jpg ----> bugall.jpg? Time = 1402394823

I have never tried the image myself. I don't know if it works. No, but the principle should be the same.

It usually takes a long time without a timestamp. Just clear the cdn cache manually.
