Try to find answer from the old thread but couldn't get what I want.
I have created the child theme. When I post my photos as Gallery, can I configure the post to auto resize all my image in Gallery to have a long edge of 600 pixel?
Or resize the image for all heigh maximum of 600 pixel?
I am looking for an alternative to have a consistency of photos viewing in the Gallery mode.
When view in individual photos:
thanks in advance.
