[Neos] Exporting Media image tags

[Nick]

Hi all

I am wondering if there is a way of preserving the Media image tags when exporting a site?
At the moment I am developing a the site on a dev machine and then putting changes (content) up to a pre-production site via export. Every time I have 
to re-tag the images, as site export doen't preserve these,  which is a bit (just tiny) frustrating so wondering if there is a better way that someone 
may know.

Many thanks
