The plugin expands the image meta by extracting data via exiftool. The default set of keywords is:
<pre><code>-MIMEType', '-FileType', '-FileName', '-ModifyDate', '-CreateDate', '-DateTimeOriginal', '-ImageHeight', '-ImageWidth', '-Aperture', '-FOV', '-ISO', '-FocalLength', '-FNumber', '-FocalLengthIn35mmFormat', '-ExposureTime', '-Copyright', '-Artist', '-Model', '-GPSLongitude#', '-GPSLatitude#', '-LensID'
