THMB FTP command

Updated May 5, 2017


This article provides information on Thumbnail (THMB) FTP command. 

Starts a file download where the server sends a thumbnail image of a remote file in the specified format.


All Serv-U versions


The THMB command allows clients to view a small thumbnail copy of an image before downloading the full image. When the THMB command is issued, the server dynamically generates thumbnails of the specified size and sends the images to the client, using far less bandwidth than would be necessary to send the whole image.
