there is no builtin way to do this that I know of. I do this in publishing blogposts from org-mode. i use a filter on links that does this. The copying code is here:
https://github.com/jkitchin/jmax/blob/master/user/blogofile.el#L115 the results of that code can be seen at http://kitchingroup.cheme.cmu.edu. I wrote about doing some of this here: http://kitchingroup.cheme.cmu.edu/blog/2013/09/28/Changing-links-to-files-so-they-work-in-a-blog/ It may not be what you want, but it might help you build your code. I hope it helps!
