Autoit Find Image and Write Text to File

I wanna do Find image on somewhere screen and write something to specific file. I dont have much experience.

If to be more descriptive; I have 3 image on screen but they are changes every 10 min or more I want it to check for image every 5 minutes. if X image there write X image appeared to file. if Y image there write Y image appeared to file. And after all of them i want to count which image how much time appeared. Like this.

I did something here.

#include <File.au3>
#include <ImageSearch2015.au3>
#RequireAdmin

HotKeySet("p", "baslat")
HotKeySet("{ESC}", "kapat")


Global $x=0,$y=0
$file = "deneme.txt"
$r= @ScriptDir & '\bu2.png'

$i = 0
Func baslat()
    While 1
        If _ImageSearch($r, 0, $x, $y, 20) = 1 Then
For $i = 1 to 10
    Next
    FileWrite("deneme.txt", $i)
Sleep(200)
$sStr = FileRead("deneme.txt")
        $sStr = StringReplace("deneme.txt", $i, $i+1)
        $oFile = FileOpen("deneme.txt", 2)
        FileWrite($oFile,$i)
        FileClose($oFile)
    Else
EndIf
WEnd
EndFunc


Func kapat()
    Exit 0
EndFunc

While 1
    Sleep(200)
WEnd
