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).
--search-recursively    Search recursively for files in subdirectories.
--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 file description, default 'Importing file'.
--comment-file=<file>   Set description to the content of <file>.
--comment-ext=<ext>     Causes the description for each file to be loaded from a
                        file with the same name, but the extension <ext>. If a
                        global description 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).
--summary=<summary>     Upload summary, description will be used if not
                        provided.
--timestamp=<timestamp> Override upload time/date, all MediaWiki timestamp
                        formats are accepted.
--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/."
