Everything is transparent when opening a .PAL file through PHP

[Hyvraine]

I use this code to unpack the pal file and make the pixel:

$color2 = unpack('H2', fread($this->pal, 0x01));

$bg_color = ImageColorAllocate($im,$rgb[0],$rgb[1],$rgb[2]);
if($color[1] == '00') ImageColorTransparent($im,$bg_color);
ImageSetPixel($im,$bg_length,$bg_y,$bg_color);

Everything is transparentttt whyyyyyy. My guess is that the 'index' or whatever you call it isn't incrementing or something.

I got it to display its palette table though. Any ideas?

I'm not really good with PHP, please halp.
