[SOLVED] Displaying an image without saving it on the server

[lemmin]

I am creating an image using the GD libraries and I want to display it without saving the actual file on the server. Noramally I would just use an image header on the page to do this, but I need information that I am accumulating while creating the image. If I made a separate file to create the image and then link to it, I wouldn't be able to get that information. Also, image resources can't be serialized or saved in a session variable.

 

Any ideas?

 

Thanks.

can you gather the data you need to make the image, save it to the session, then link to a file that uses that session info to make/display the image?

I can't do that because the information is collected per pixel as I create the image.

 

Thanks for the idea, though.

depending on how big the image is, you can store the image into a session variable:

 

session_start();
ob_start();
imagepng($im);
imagedestroy($im);
$_SESSION['image'] = ob_get_clean();

It works! Thank you!
