I am seeing the thumbnails, coming over a network drive with about 600 – 800 images per folder it does take a little while for the first time. I didn’t know it automatically created the thumbnails. I seen if you right click it has generate thumbnails, so I was thinking you can create some. I think adobe bridge is like this if I remember. I notice once I view the folder once the second time around it looks like it is much faster.
I really enjoy the app great work.
