gd and GET limitations

[Nargler]

Does anyone know a way to pass parameters to an gd image generation script other then using http GET parameters?

I'm generating an image with dynamic text in the usual way

<img src="generateimage.php?text=<long string of text>">

I'm finding myself occasionally hitting up against the 2083 char limit in IE and related browsers and my script isn't executed at all.

Is there a way pass large parameters to a script and display the image in the browser in one swoop?

You could pass the id of a database record, or the name of a text file

Thanks for the ideas, got me out of the rut I was in.

I decided to use a session variable to store the parameter before calling the image generating function through the 'img src' tag. In the function itself the session variable is checked for and accessed as required, side stepping the GET limit nicely.
