i have read exclusively posts concerning error here, none address specific issue, because mine displaying small size images not images , above 10kb. 10kb far cry projected average image size uploaded later. please help.

if $d_resource binary image data

you should used imagejpeg or imagegif or other series functions, rather echo

see output image browser or file - php
