VM3.0.2: How to change the folder location of virtuemart's image files?

[hhtmp88]

Dear all,

Assuming that:
-- Joomla is installed at: public_html/joom
-- Virtuemart's original image file location: public_html/joom/images/stories/virtuemart

How to change Virtuemart's image file location to
public_html/joomfiles/virtuemart/vm_media

Thanks for any kind of help!

Go to

virtuemart/configuration/templates

Media Files Settings
General Assets URL    
Category Media URL    
Product Media URL    
Manufacturer Media URL    
Vendor Media URL

change to where you want to store them

You may need to move your original images to the new location!

Thanks Hutson for your comments!
but...

pls. note that I installed Joomla in the folder "public_html/joom"
and I want the media folder outside "joom", i.e. "public_html/joomfiles"
and except "safe path" which can input full directory path, all other path must be specified under Joomla's installation directory "joom", e.g. "images/stories/virtuemart/Category" for "Category Media URL", which is actually "public_html/joom/images/stories/virtuemart/Category"
-> if I want it to be  "public_html/joomfiles/virtuemart/vm_media/Categories", which is outside Joomla's installation directory "joom", How to do?

Thanks for any kind of help!
