Because, the intention is to convert a php blog/news to html
and then reupload it.
it has 50+ external hosts. mainly because of various subdomain of image
hosts.
So if those external resources are in separate folder, then the url to te
actual blog will look messy after uploading again.

Since it'll be online, I can just skip all external resources. but problem is,
image hosts tend to turn to stop working.

Many of my images are already lost, which were in tinypic.
I don't want the same for other images and want to host those locally.

Hope that clears my situation.

Thanks for taking the time to read and reply to my question.
