It works from your reference picture, so a photo stays a photo and an illustration stays an illustration.

It uses <code>CreateList</code>/<code>GetItemFromList</code>, <code>StringFormat</code> + <code>StringCompare</code>, a lazy <code>If/Else Switch</code> and <code>RegexReplace</code>.</li></ul>
