Here is a fun code for making images with white bg transparent. Well it can work with any bg but you need to adjust the color values accordingly. Works best with plain dual colors. I searched for this kind of code a lot but unable to find one ...see if this helps someone.
<?php
function transparentImage($src){ $r1=80;
$g1=80;
$b1=80;
for($x = 0; $x < imagesx($src); ++$x)
{
for($y = 0; $y < imagesy($src); ++$y)
{
$color=imagecolorat($src, $x, $y);
$r = ($color >> 16) & 0xFF;
$g = ($color >> 8) & 0xFF;
$b = $color & 0xFF;
for($i=0;$i<270;$i++){
if($r.$g.$b==($r1+$i).($g1+$i).($b1+$i)){
$trans_colour = imagecolorallocatealpha($src, 0, 0, 0, 127);
imagefill($src, $x, $y, $trans_colour);
}
}
}
}
return $src;
}
$image='abc/abc.jpg';
$src = imagecreatefromjpeg($image);
$src=transparentImage($src); ?>
