Hi,

You could re-write the transformation which you use in the Media gallery web part's Properties. It defines the layout of items of media library.

The transformation which we use on the sample site is: Community.Transformations.MediaLibrary which displays the files in row.

Please see here: [url=http://devnet.kentico.com/docs/devguide/writing_transformations.htm ]writing transformation[/url]for more information about transformations.
