pushing a button makes appear a picture at the computerscreen

oh thanks, havent seen before that arduino hasnt a display..
but thats exactly i asked for the whole time, how to tell the pc do it...

next try:

now im using python to let the pictures appear and im writing the code in komodo.

def (btn_i):    # picture to show when button pushed
     ....1, DEC = btn_1
     ...?
       
import serial

ser = serial.Serial('/dev/ttyUSB0', 9600) 

var = 1
while var == 1:
    if ser.inWaiting() > 0:
    if ser.readline == "btn_2":
    form.show_form(placement, bordertype, name)
    //to Show the image?
    if.....
    form.hide_form(.....)
    //is it possible to hide the image. or is it already included in the arduino code?
    
    elif ser.readline == "btn_3":
    print-3.jpeg //better just use print?
    
    elif ser.readline == "btn_4":
    print-4.jpeg
    
    elif ser.readline == "btn_5":
    print-5.jpeg
    
    elif ser.readline == "btn_6":
    print-6.jpeg
    
    elif ser.readline == "btn_7":
    print-7.jpeg
    
    elif ser.readline == "btn_8":
    print-8.jpeg
