How do I put the text in a pictureBox and be able to save the text in picture after?

I found two methods but there is a problem in each case.

- With method Picture1.print "text". I wish the user determine the coordinates (x, y) where he want put her text (Mouse Click) on picturebox.

- And with the method Drag & Drop textbox on picturebox, how to save picture after drop text on picturebox. With PaintPicture, it's impossible (save picture on picture).

Thanks for any suggestions…
