create a new folder and save image files in that folder

Did you ever try to evaluate, how many types and methods are there in FCL? What happens if you ask a question on each and every of your everyday chores? And, with such approach, there is no hope that you learn something and improve your future work, because learning how to create a folder cannot help, say, to show a picture.
 
Therefore, you really need help on a very different subject: Microsoft Q209354.
