How to ensure images load?


Recommended Posts

I am trying to figure out how to make sure that all images that I want to form a multi-part signature for a forum actually load and display. Is there a way of doing this?


This code wasn't written by me, but I did modify it slightly, to suit my purposes. It randomly picks an image to send to my signature and the sig loads a few other small images to box it in, however, the majority of the time the random image does not display. All of the other images do, so what can I do to ensure all images display?


This code is called in an HTML <IMG> tag.



srand((double)microtime()*1000000); //random number seed
$num = rand(16, 200); //random number generation range
$img = imagecreatefrompng("$num.png"); //make an image variable from a png image
$color = ImageColorAllocate($img, 255, 214, 12); //define a color for the text
// imagestring($img, 2, 7, 92, "text if I want it", $color); // position the text
header('content-type: image/png'); //tells the browser that it's receiving a png image
imagepng($img); //deliver the final png image
imagedestroy($img); //memory cleanup
