I am using the version of GD packaged with php 4.3.x for windows and am
having a problem with opening images and not being able to lock them.
As soon as I have multiple users requiring the same dynamically generated
image, the image sent to the browser is all distorted and blurred but only
happens when multiple users are accessing the exact same dynamically
generated image. I would like to lock the images before processing but the
functions for gd (eg. imagecreatefromgif() require a filename string and not
a resource handle created by flock().
Any insight would be appreciated.
