If allow_url_fopen is enabled you should be able to retrieve & alter it
using the GD functions.

Are you looking to modify the PNG on the server
or the client within the browser ?

If you want to modify Server side then look at the GD library. Here
are two good links for that
www.libgd.org/Main_Page
- GD - Open Source library
http://www.codebeach.com/index.asp?t...ubcategoryID=4
- GD Tutorials

If you want to modify within the browser you might
consider use of an ActiveX component like our own
MetaDraw 3 OCX ( see www.Bennet-Tec.com) , or ImageMan ( from
DataTechniques www.Data-Tech.com ).
* MetaDraw will allow resizing, drawing / annotation, ..
by client side script or even ( if you allow ) by the
end-user with his mouse within the browser. * ImageMan
is great for things like Resizing, Rotation, Color depth
manipulation, Gamma correction, ...

actually i was able to work it out using this code:
$ch = curl_init();
$timeout = 0;
curl_setopt ($ch, CURLOPT_URL, $xmyurl);
curl_setopt ($ch, CURLOPT_CONNECT TIMEOUT, $timeout);
// Getting binary data
curl_setopt($ch , CURLOPT_RETURNT RANSFER, 1);
curl_setopt($ch , CURLOPT_BINARYT RANSFER, 1);
$image = curl_exec($ch);
curl_close($ch) ;

and display the output this way:
header("Content-type: image/png");
echo $image;

now what i want to do is edit that $image as png file using gd. i
tried it:
header('Content-type: image/png');
$xbase = @imagecreatetru ecolor(130,168) ;
$xback=imagecol orallocate($xba se, 39,138,8); //green
imagefill($xbas e,0,0,$xback);
imagecopy($xbas e,$image,0, 28, 0, 0, 130,140);
imagepng($xbase );

what supposed to happen is $image should be inside $xbase frame.
however it doesnt work, instead only $xbase is showing. what to do
with this?

actually i come up with this:
ch = curl_init();
$timeout = 0;
curl_setopt ($ch, CURLOPT_URL, $xmyurl);
curl_setopt ($ch, CURLOPT_CONNECT TIMEOUT, $timeout);
// Getting binary data
curl_setopt($ch , CURLOPT_RETURNT RANSFER, 1);
curl_setopt($ch , CURLOPT_BINARYT RANSFER, 1);
$image = curl_exec($ch);
curl_close($ch) ;

An image resource is NOT the raw data. Get the image, store it temporarily
on you computer, create an image resource with an imagecreatefrom *()
function and you've got it.
