How to read the content of a directory?

Hi,

I´m trying to make an image album and i´d like to not worry about file names and the like.
I know i can name the files with numbers, for example, and use a buckle to read them one by one, but i don´t want to.

I´d like to know if it´s possible to read the content of a directory with AS.

Hope you gurus can help out.
Thanks in advance.
