using imagegif

[Garrett_44]

Hello

Can anyone tell me how to force recreate the image when you use this...

>imagegif($image);

instead of taking the last image from the cache?

any help much appreciated!

Hello,
I had the similar problem before. Here's the thread

[Garrett_44]

yep i'm creating abstract random images on the fly, but essential same problem. That header code seems to do the trick! thanks!

got one or two other things i am trying to do..
in the code that produces my image (see below) i am creating a random positioned and sized grey triangle with fill on a white background (got me?). trouble is from time to time my triangle has no fill and occasionally the image is grey with a white triangle and i have no idea why its doing this? if any one has an idea i would greatly appreciate it!!

a+
Garrett

ImagePolygon($image, $vertices, 3, $grey1); // draw pentagon
ImageFillToBorder($image, $the_middle_x, $the_middle_y, $grey1, $grey1); // fill pentagon with green until it reaches grey border

//visualise image
