Merge images / add logo

Hi there,
I was wondering what's the quickest way to put a (transp-PNG)
over a picture?
I have a code, but i guess it's sloppy. And it's slow.
(Code below this message)
Could anyone help me out on this?
Thanks
Greetings Frizzle.

$img_id = substr( '0000000000'.$_GET['id'], -10, 10);
$info = getimagesize($img_id.".jpg");
$photo = imagecreatetruecolor($info[0], $info[1]);
$pic = imagecreatefromjpeg($img_id.".jpg");
imagecopy($photo, $pic, 0, 0, 0, 0, $info[0], $info[1]);
$logo = imagecreatefrompng("photo_logo.png");
imagecopy($photo, $logo, 20, 30, 0, 0, 128, 20);
header("Content-type: image/jpeg");
imagejpeg($photo , "", 90);
imagedestroy($photo);

Re: Merge images / add logo
I noticed that Message-ID:
<1121981492.298088.152490@f14g2000cwb.googlegroups. com> from frizzle
contained the following:

Funnily enough, I've been working on exactly this today. It's a first
hack so is probably messy and also a bit slow. Best to create the image
on upload then save it.

Re: Merge images / add logo
Dude,
that's a great script!
Too bad, this isn't what i intended to create.
I have my logo with colors & transparency as a PNG file,
all i want to do is put it on top of a photo.
The way i'm doing it now is slow, and i believe i'm making
a few steps to many ...
Again, compliments with your script!
Frizzle.

Re: Merge images / add logo
Hmm thanks for the effort Justin,
but all i need is to combine 2 images, no transparency
or whatever.
It's probably just a very simple script ...
Thanks anyway!

Frizzle must think this is a web forum :-)

I don't believe you are that familiar with how usenet and the majority
of newsreaders work. What you did is unlikely to achieve your goal.
A more typical approach would be to add information, especially
concerning things you've tried to solve it on your own, and the results
from those. You *have* been working on it, haven't you?

Re: Merge images / add logo
Yes of course i have!
I came here, because i really couldn't figure out the answer.
I pasted the script in my original post, so other people could
see what i have sofra.
I tried to change it etc. etc. but nothing seemed to work, i only
came up with a black image, the size of the picture with the logo
on it, but not what i wanted: only the JPG photo, with a transp-PNG
logo over it, PHP doesn't need to render any extra opacity or
whatever.
I've given as much as information as i have now ....
If there's anyone willing to help me, and needs some more info on
this, * please* ask me ...
I did not intend to abuse the usnetgroups or whatever...
