Re: [PHP] image generation issues

Adrian,
If you're using the code displayed, you need to use $im before you destroy
it.
If you want to deal with it as a .png then use:
ImagePNG($im,"some_name.png",100);
and then pick up the file anytime using
<img src="some_name.png">
You can later remove it from the server using:
unlink("some_name.png");
hope this helps.
Hugh
