Thanks for the reply.
By the Add Gallery window, I can not exclude photos!(See the function not standing.)
Have then tested at the Manage Galleries dashboard, If I search the photo with the search function, I can not exclude a photo.
If I go to the folder where the photo is, then I can exclude it.
I used to be able to do this, for me it is easy with the search function, because I have more than 1500 photos on my website.
thanks,
I have the same problem.
Last version is better!
