Answer 1

The Indexes option sets whether you can "browse" the directory or not. If indexes is set to plus, and the directory has no index.html or index.php (of whatever) file, it will show the contents of the directory just like your filemanager would do. So if there are ten images in there, it simply shows them as a list with links to the actual image. You can click them and open them.

Most of the time this is not what you want. You don't want others to see what is inside that folder. So then you turn it off with -Indexes.
