I cam across the same issue and did some minor debugging.
I see that ord($data{0}) on load() function of CGIFIMAGE class returns 0x47 
resulting
in this message. 
I hope that gives some pointer. I am attempting to fix this myself. will update 
if I
come to something. Please mail me if a solution is found.

You can easily fix this issue by replacing the function _parsegif from fpdf 
version 
1.6. Here's the replacement code:

function _parsegif($file)
{
    //Extract info from a GIF file (via PNG conversion)
    if(!function_exists('imagepng'))
        $this->Error('GD extension is required for GIF support');
    if(!function_exists('imagecreatefromgif'))
        $this->Error('GD has no GIF read support');
    $im=imagecreatefromgif($file);
    if(!$im)
        $this->Error('Missing or incorrect image file: '.$file);
    imageinterlace($im,0);
    $tmp=tempnam('.','gif');
    if(!$tmp)
        $this->Error('Unable to create a temporary file');
    if(!imagepng($im,$tmp))
        $this->Error('Error while saving to temporary file');
    imagedestroy($im);
    $info=$this->_parsepng($tmp);
    unlink($tmp);
    return $info;
}

I had thought of this solution but this is a temporary solution and it involves
expensive file operations which we should rather avoid esp if we are creating a 
pdf
with lots of gif images. There should be a way to do this without the file 
operations.

This can easily be fixed! PHP5 seems to have changed the order of assigning a 
value
to a variable when it is passed by reference.

I have attached my gif.php where I have done the needed changes.

There were some function calls by reference that got called like this:
$this->skipExt($data, $len = 0)

In PHP4, $len first got the value 0 and then the function will be called with a
reference to $len.

In PHP5, the function get's called with a reference to $len and THEN give it the
value 0 and overwrite the needed value...

Hi,

Why it doesn't support image files? Each time, it gives me no_img.gif. The 
location to my image is correct.
