How to show images in a sequence in python

I have a list of images

and I want them to be shown one at a time and in order and that each time the program starts, the following is displayed

Example:

Start the program 1 time

Img1

Start the program 2 times

Img2 ...

and so on

I tried with the for loop and it shows me the position in the list

[CORRECTION AFTER COMMENTS]

I went back to check the loop the entry is this:

def imgor():
          for imagen in Imagenes:
               imagen
               print imagen
     Imagenfin=imgor()
     lbl=Label(root,image=imgor()).place(x=00,y=00)

and the output is this:

    >>> pyimage1
pyimage2
pyimage3
pyimage4
pyimage5
pyimage7
pyimage8
pyimage9
pyimage10
pyimage1
pyimage2
pyimage3
pyimage4
pyimage5
pyimage7
pyimage8
pyimage9
pyimage10

but at the end a black screen opens

[SECOND CORRECTION]

from Tkinter import*
def p():
     root = Tk()
     sp = Ventana(root)
     sp.config(bg="black")
     Img1=PhotoImage(file="Libre.gif")
     Img2=PhotoImage(file="Soy.gif")
     Img3=PhotoImage(file="universe.gif")
     Img4=PhotoImage(file="BBN.gif")
     Img5=PhotoImage(file="tr.gif")
     Img6=PhotoImage(file="final.gif")
     Img7=PhotoImage(file="alc.gif")
     Img8=PhotoImage(file="cer.gif")
     Img9=PhotoImage(file="at.gif")
     Img10=PhotoImage(file="bos.gif")
     Img11=PhotoImage(file="se.gif")
     #Img=PhotoImage(file=".gif")
     Imagenes=[Img1,Img2,Img3,Img4,Img5,Img7,Img8,Img9,Img10]
     def imgor():
          for imagen in Imagenes:
              imagen
              print imagen
     Imagenfin=imgor()
     lbl=Label(root,image=imgor()).place(x=00,y=00)
     root.after(6010,root.destroy())
     root.mainloop()

now if there is the complete code
