This is not a Zope problem but a caching problem:

  Your browser (or maybe a proxy in between) has cached the image.
  When it needs the image later again, it fetches it from the cache.

  With many browsers, you can use "shift-reload" to force the browser
  to refetch the image from the server. You will see, it is the
  new image.

What can you do?

  *  configure your browser to always check freshness of the image

  *  configure Zope to send "Expires" headers for images
