How to solve browser image caching issue right after uploading a new image

This is trivial stuff. You only need to give some 'flag' (either by session or other params), and if the flag is on, at the redirected page (success page/controller) you response with some redirect to the same page with refresh function. Unless you did use some fancy stuff of cache mechanism, i don't see playing with HTTP header-cache is the solution.
