Taking care of embedded files

System

Hi,

How do you guys take care of embedded files like images etc inside the HTML?
When I'm deleting/expiring/Archiving the HTMLs, I dont know what to do with the images.
There is a possibility that same images are shared by various HTMLs, so just removing the image when the HTML is removed could be dangerous.

Another issue is getting the image names itself.
I've 2 types if HTMLs
a) Generated thru templates: I can get the image names from the DCRs.
b) Directly uploaded HTMLs (images are uploaded separately into correct folders by the user: )

Taking care of the type (b) HTMLs is seems more difficult because I'll need to traverse the HTML and look for the 'img' tags inside the HTML.

Whats the best practice to take care of this?

TIA
