How can I list all image files and upload them to FTP?

Question

How can I easy do that:

I have correctly saved all file.directories here: ArrayList fileList = new ArrayList();

And how can I upload them using this method?

public static FTPClient con = null;

public static void upload(String path, String fileName)
{
    try
    {
        con = new FTPClient();
        con.connect("server");

        if (con.login("login", "pass"))
        {

            con.enterLocalPassiveMode(); // important!
            con.setFileType(FTP.BINARY_FILE_TYPE);

            String data = path;

            FileInputStream in = new FileInputStream(new File(data));
            boolean result = con.storeFile("/Test/" + fileName, in);
            in.close();

            con.logout();
            con.disconnect();
        }
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }
}
