order of my pictures in a diaporama ( using an USB key )

[famille vanderhulst]

Hello everybody,

Here is my question, could you give me some advice ? :
I would like to show a diaporama of some pictures on my TV ( model 32PFL5606H/12 ) .
I use an USB key . When I open my folder, the pictures appears in a incomprehensible order .
How to do to view pictures on a normal and understandable order ( alphabetical or so ) ?

Thanks in advance for your answers
Emilie
