Imports images and other media files into the wiki
USAGE: php importImages.php [options] <dir>

<dir> : Path to the directory containing images to be imported

Options:
--extensions=<exts>     Comma-separated list of allowable extensions, defaults to \$wgFileExtensions
--overwrite             Overwrite existing images with the same name (default is to skip them)
--limit=<num>           Limit the number of images to process. Ignored or skipped images are not counted.
--from=<name>           Ignore all files until the one with the given name. Useful for resuming
                                                aborted imports. <name> should be the file's canonical database form.
--skip-dupes            Skip images that were already uploaded under a different name (check SHA1)
--sleep=<sec>           Sleep between files. Useful mostly for debugging.
--user=<username>       Set username of uploader, default 'Maintenance script'
--check-userblock       Check if the user got blocked during import.
--comment=<text>        Set upload summary comment, default 'Importing image file'.
--comment-file=<file>   Set upload summary comment the the content of <file>.
--comment-ext=<ext>     Causes the comment for each file to be loaded from a file with the same name
                        but the extension <ext>. If a global comment is also given, it is appended.
--license=<code>        Use an optional license template
--dry                   Dry run, don't import anything
--protect=<protect>     Specify the protect value (autoconfirmed,sysop)
--unprotect             Unprotects all uploaded images
--source-wiki-url   if specified, take User and Comment data for each imported file from this URL.
                                        For example, --source-wiki-url="http://en.wikipedia.org/"
