Hello Folks,
I have the following code that displays files and directoies within a
directory and display the thumbnail exif data if it exists. And
everybody was happy with that for a few hours.
Now I have been asked to add a button that downloads the files in the
directory and I can't quite get my head round it.
Could someone point me in the right direction please.
