and this is ImageSearch.au3

      if $result > 0 Then
       return $i
      EndIf
  Next
WEnd
return 0
EndFunc

and this is my Program just like this

#include <ImageSearch.au3>
$x1 = 0
$y1 = 0
$ImageToSearch = @Scriptdir &"\Image.bmp"
HotKeySet("x","_exit")
Sleep(7000)
$i = 1
While $i < 100000
      $res1 = _ImageSearch ($ImageToSearch ,1,$x1,$y1,100)
   If ($res1 = 1) Then
   Exit
   Else
   Call("_ChangeDesktop")
   EndIf
WEnd
Func _exit()
Exit
EndFunc

Func _ChangeDesktop()
   ;Dosomething to change desktop
   $i = $i + 1
EndFunc

Absolutely my program will load the Image.bmp in HardDrive 100000 times

I want to load the image to some where on RAM to low down the time of reading from Hard Drive

Please help

Sorry about my bad English!
