ImageGif problem in PHP4

[Anon]

I put together a function to resize uploaded images. It worked fine in php3, but now in php4 using GD library version "between 1.3 and 1.6.1" (as phpinfo() says), I get the following error:

Warning: imagegif: unable to open '7.gif' for writing in functions.php4 on line 38
ImageGif() is being used in the following context:

function
resize($sourceimage,$destinationimage, $newwidth, $newheight){

    $oldimage = ImageCreateFromGif($sourceimage);

    $size = GetImageSize($sourceimage);

    $newimage = ImageCreate($newwidth,$newheight);

    ImageCopyResized($newimage, $oldimage, 0,0,0,0,$newwidth,$newheight,$si$
    ImageGif($newimage, $destinationimage);

}
Does anyone know what the problem is?

I figured it out...
The problem was I didn't have the permissions set right for that directory & the script didn't have write access.

sorry but gd in php4 doesn't support gif anymore

but you can use png instead

Hey, I have just installed PHP on my server, and I have been getting the same problem with regard to creating the image. I assume it has to do with permissions. If I give a "everyone" access permission to a folder, I can save the image into that folder, but any other type of permission has not worked. I was wondering if you had any suggestions with regard to this, I from your question on the PHP page that you have had some experience with this.
THANKS
