Generating device specific thumbnails

A method for generating device specific thumbnails may includes receiving one or more databases on a computing device from a mobile electronic device where the one or more databases include a key file and a data file. The data file may include picture data and the key file may include an index to the picture data. Also, the method may include generating a synchronization set on the computing device wherein the synchronization set includes one or more picture files to be stored on the mobile electronic device. The one or more databases may be transformed to one or more updated databases, wherein the transforming includes updating the key file to index pictures included in the synchronization set and updating the data file to include thumbnails of the pictures included in the synchronization set. The one or more updated databases may be transmitted to the mobile electronic device.
