This may be not GD problem but connection problem. Your browser is requesting
many (maybe all) images at the same time. Probably your server is limiting
the amount of connections so the browser gets the error instead of the image.
Try increasing your server connection limits or configure your browser to
limit count of connections opened at one time (it should queue image requests).
