How to keep only last 3 versions of attachment in confluence

[maroom1]

Hi,

We are trying to upload the design images into confluence, every 3 days typically our images are changing, we dont use the old images at all.  Is there anyway we can restrict only last 3 versions available, remove the oldest one all the time whenever a new version is available. (any plugin. auto process, confluence settings I was looking for) 

Thank you for your help.

This is an old app for Confluence that is no longer searchable in the marketplace, but it does what you are looking for. I am running Confluence 6.15 and it still works.
