[Mediawiki-l] location of images

[aretai aretai]

Hi,

Just a small problem. I'm trying to create a script that'll export the wiki
pages (sth similar to Special:Export), there is one problem because of the
images. When using Special:Export we get a content with a

[[Image:imagefile.imageextension]]

I'd like to have a link to an image located on my host instead. All images
are stored in the images directory within wiki. Below are some
subdirectories: d, f, etc.

Is there any rule where is given image placed while being uploaded?

Regards,
Aretai
