Make thumbnails of feature classes using arcpy

Hi All,

I know arcpy can be used to make thumbnails from MXDs, but what about using feature classes or rasters? I have thousands of feature classes / rasters that I need to make thumbnails for and don't want to have to manually do this within ArcCatalog one at a time.

Any thoughts on how to achieve this? I have code to already list the spatial datasets, just need coding to generate thumbnails that will be incorporated into metadata documents.

Regards,

Craig
