ImgApp was updated to v1.2.0. New method was added.
3. updateThumbnail()
Overview
This method is for updating thumbnail of files on Google Drive using images you selected.
Description
For example, zip files don’t have the thumbnail on Google Drive. An icon is shown as the thumbnail. For the most files, Google Drive can create automatically each thumbnail. But there are sometimes files which cannot be created the thumbnail. Zip file is also one of them. In order to add and update thumbnails to such files, I added this method.
Demo
This is a demonstration for this method. The thumbnails of zip files are updated.
