For now the following has been implemented with regards to thumbnail and on sandbox:
1. If a word document doesn't have thumbnail, we will display a word file icon.
2.  For pdf files without icons, we will display a pdf file icon
3. Any file that has an archive format eg .zip etc, we will display a zip file icon.
4. For all other file formats not covered above, we will display a normal file icon.
5.  Finally for files under embargo/lease irrespective of whether they have thumbnails or not, they will display a file icon for anyone who is not the owner or an admin.
