Did you use quotes around the URL when trying to access the image?

Subject: Re: [PHP] Importing a GIF image and making it transparent
|
| Thanks to those who replied, i finally worked it out - the script has been
| pasted below just incase anyone is sifting through the list archives
looking
| for the same thing. One thing though, my server doesn't allow me to open
a
| GIF file through HTTP - ie this doesn't work
|
| $image = ImageCreateFromGif(http://www.severname.com/image.gif);
|
| Does anyone know of a server/hosting company that will allow me to do
this?
|
|
| The script:
|
| <?
|
| $id = ImageCreateFromGif("image.gif");
|
| $trans = imagecolorexact($id, 120, 100, 90);
|
| imagecolortransparent($id, $trans);
|
| ImageGIF($id,"newimage.gif");
|
| echo "done";
|
| ?>
