Hi bbcgraphics,
Please try thie way.
1. Open file "\CuteSoft_Client\Gallery\Layout\Classic\Code.js"
2. Find section below
var img=this.Browser.CreateThumbnail(photo.Thumbnail,Math.floor(photo.Width * scale),Math.floor(photo.Height * scale));
3. The red code is the width and height of the thumbnai. You can change it directly.
Like
var img=this.Browser.CreateThumbnail(photo.Thumbnail,Math.floor(128),Math.floor(96));
Regards,
ken
