Hello Alexey,
Thank you for your kind answer.
I tried your instructions in order, but when I select two photographs and click 'Look Through', software gives me arbitrary random photographs. For example, I do select 'IMG_01' and 'IMG_02' but software showing 'IMG_47' and 'IMG_93'. I couldn't figure out why.
Appriciate for your further help.
Thank you.
AO.
