it finds image with:
$res = _imagesearch( "Killed.jpg", 1, $i, $o, 100)
but it does not with
$res = _imagesearch("*TransBlack"&"Killed.jpg", 1, $i, $o, 100)
reson i need to get it trans is because text's background may change sometimes and the background on pic that needst to be transparent is black=0x000000
