After some specific period of time all sessions are being expired.
I have checked session.gc_maxlifetime in php.ini it's more than 20 hours.

Is anybody have solution to this problem?
...

ok..thank you very much..

But Suresh,at given position pixel may be of transparent color no?
if we have provided x and y co-ordinates of image where there is transparency
what "ImageColorAt" function will return?
...

And then merge all those transparent images in that container.
I think it should work.

$image=imagecreatefrompng("gans.png"); //transparent png image
$bcolor_at = ImageColorAt ($image,$i, $j);
