Re: save file from outside url

Thanks for responing Jason! There is other code in there for updating some database entries and producing a confirmation page, but I had them working perfectly before I added the image code below. Only when acessing the outside script and saving to file did it start doing the odd things. I didn't write the image creation script, only hard coded in some values for font and bg colors in it. I have attached that script at the bottom of this, away from everything else. Maybe a header problem from that script? Any idea what 427 is from? Thanks for all your help! The $image_url is like this - "$rollover_image_url = "http://www.anysite.com//pngmake.php?msg=" . $rollover .
