//When converting an image from gif to jpeg or png, you need to create an
intermediate image the same size as you want output. The following should
work, but it's not tested.
hope this helps,
Hugh
<?php
$size=getimagesize($filename); // this will get the x & y dimensions and the
file type (gif, jpeg, etc.)
if ($size[2]==1) $orig_img = imagecreatefromgif($filename);
if ($size[2]==2) $orig_img = imagecreatefromjpeg($filename);
$destination_image=imagecreatetruecolor ( $size[0], $size[1]); //
intermediate image the same size as orig_img
imagecopy ( $destination_image, $orig_img, 0, 0, 0, 0, $size[0], $size[1]);
header("content-type: image/jpeg"); // needed only if you want to use the
data stream.
imagejpeg($destination_image,'$new_file_name', 80); // if you just want the
output, you can leave out the $new_file_name.
imagedestroy($orig_img);
imagedestroy($destination_image);
?>
