Hello,

Thank you for your post

Yes, you can set (or change) the Image Gallery sorting. All you need to do is set the SelectNodesOrderBy property of the DataList "ImageGalleryThumbnailList" located at the user control ~/ImageGallery/ImageGalleryThumbnails.ascx, for example: SelectNodesOrderBy="AliasPath DESC"

If I can be of any further help, please let me know.

Best Regards
