Abstract
An image management method and system are disclosed which can increase user convenience by reducing a display time of thumbnails in a DLNA system. The DLNA system includes a digital media server for generating a thumbnail group image using thumbnails corresponding to at least one original image file and transmitting the thumbnail group image, and a digital media player for receiving the thumbnail group image from the digital media server and requesting the digital media server to transmit an original image file corresponding to a selected thumbnail among thumbnails included the thumbnail group image.

A digital media server in a wireless network comprising:
- a thumbnail group image generator configured to:
- generate thumbnails by reducing size of at least one original image file, and
- generate a thumbnail group image by combining the thumbnails together;
- a thumbnail index generator configured to generate indexes for the thumbnails corresponding to the at least one original image file;
- a communication interface configured to:
- when a first request for an image list of the at least one original image file is received from a digital media player, transmit the thumbnail group image and the indexes to the digital media player, and
- when any thumbnail included in the thumbnail group image is selected, receive a second request to transmit an original image file corresponding to the selected thumbnail from the digital media player;
- and
- a controller configured to:
- determine the original image file corresponding to the selected thumbnail from the digital media player, and generate a message including a Uniform Resource Identifier (URI) of the original image file corresponding to the selected thumbnail, in response to the second request from the digital media player, and
- control the communication interface to transmit the message to the digital media player;
- wherein the digital media player receives the message, accesses the URI included in the message, and downloads the original image file.
