I suppose you are trying to resize an image (which has alpha). It works
well here.
See:
http://blog.thepimp.net/misc/40069_res.png
You inverted the width/height arguments in imagecopyresampled. The
correct script should be (size * 1.2 here):
$im = imagecreatefrompng($sourcefile);
$sourcefile_width = imagesx($im);
$sourcefile_height = imagesy($im);
$sourcefile_new_width = $sourcefile_width * 1.2;
$sourcefile_new_height = $sourcefile_height * 1.2;
$im_dest = imagecreatetruecolor ($sourcefile_new_width,
$sourcefile_new_height);
imagealphablending($im_dest, false);
imagecopyresampled($im_dest, $im, 0, 0, 0, 0, $sourcefile_new_width,
$sourcefile_new_height,
$sourcefile_width, $sourcefile_height);
imagesavealpha($im_dest, true);
imagepng($im_dest, $destfile);
imagedestroy($im_dest);
I close the bug (no bug > bogus), feel free to reopen it if I
misunderstand your problem,

after closer inspection of the png i noticed that it is possibly
transfering correctly,. As you can see what appears to be a bit of the
picture on the bottom left, but it is not resizing the png at all.
rather overlaying without resizing the overlayed image.
