Each album has a blank index.php file! Nowhere did I find information on how and what I could use this file for. I tried to customize this file ,but there is no effect. Also, deleting it has no effect, everything works without it. Can anyone explain how to use this index.php file?
For some systems that may be improperly set up, pointing a web browser at your image storage location could display (similar to your attached image) all the images located there. That small index.php file ensures that they only receive a blank page.
