Answer 1

To get the thumbnail of a file stored on Google Drive you have to send a GET request to the file endpoint and then check its thumbnailLink property:

https://developers.google.com/drive/v2/reference/files/get

Regardless of the format of the thumbnail URL, as long as you use the value returned in the file metadata you should be fine.

Please take into account that thumbnail URLs expire after a certain time.
