/**
* Insert an image upload into the mediawiki database tables. If the
* image insert was successful, a page showing the wiki text for their
* image is shown. Otherwise, if the image file name already exists in
* the database, a conflict page is returned to the user.
*
* @param $type string with either 'overwrite' or blank -- specifies
* whether to force-overwrite an existing image
* @param $name filename chosen by user for uploaded image
* @param $mwname filename of the file in mediawiki DB
* @param $fromIIA true iff source of call is Special:IntroImageAdder
* @param $image_comment a comment attached to the image upload (only
* used if $fromIIA == true)
* @return outputs either a wikitext results page (if image filename
* didn't exist or force overwrite was selected) or a conflict page.
* Returns an error string or empty string if no error.
