Description:
------------
The problem is that when reading a transparant color from an existing image in some cases can't be used to set the transparant color for new images.

Reproduce code:
---------------
$im = imagecreatefromgif("image.gif");

$trnprt_indx  = imagecolortransparent($im); 
$trnprt_color = @imagecolorsforindex($im, $trnprt_indx); // error line


Expected result:
----------------
imagecolorsforindex() [<a href='function.imagecolorsforindex'>function.imagecolorsforindex</a>]: Color index 251 out of range

if the image is a palette image and has only 10 colors, trying to use the color 11 will obviously fail.

er?? the current image will be copied to a new image (thumb) but i'd like to keep the current 'transparant' color, but this gives an error... looks like the index for the transparant color (current image) doesn't exists in the color palette... (current image)
