refreshImageMetadata.php file is a maintenance script to refresh image metadata fields.

--force Reload metadata from file even if the metadata looks ok.
--broken-only Only fix really broken records, leave old but still compatible records alone.
--verbose Output extra information about each upgraded/non-upgraded file.
--start="file_name" Name of file to start with. Spaces must be replaced by underscores, since the parameter will be used to match the file name as stored in the database.
--end="file_name" Name of file to end with.
--mediatype="media type" Only refresh files with this media type, e.g. BITMAP, UNKNOWN etc.
--mime="MIME type" Only refresh files with this MIME type. Can accept wild-card 'image/*'. Potentially inefficient unless mediatype is also specified
