Watermark Attached Images

This hack adds a watermark to attached images. The watermark, as specified by your own .png image, is added on image download, not when the image is attached. Requires GD2. Do not even try installing if you don't have GD2.

I did delete those 2 lines, and it still did not do me any good,

first i deleted

PHP Code:

header("Content-disposition:$attachment filename=$attachmentinfo[filename]");
header("Content-Length: ".strlen($attachmentinfo[filedata])); 


then i replaced,

PHP Code:

if ($extension=="gif") {
  header("Content-type: image/gif");
} elseif ($extension=="jpg" or $extension=="jpeg") {
  header("Content-type: image/pjpeg");
} elseif ($extension=="png") {
  header("Content-type: image/png");
} elseif ($extension=="pdf") {
    header("Content-type: application/pdf");
} else {
  header("Content-type: unknown/unknown");
}
echo $attachmentinfo[filedata]; 


with

PHP Code:

$isimage = true;
switch ($extension)
{
    case "gif":
        $header = "image/gif";
        break;
    case "jpg":
    case "jpeg":
        $header = "image/jpeg";
        break;
    case "png":
        $header = "image/png";
        break;
    case "pdf":
        $header = "application/pdf";
        $isimage = false;
        break;
    default:
        $isimage = false;
        $header = "unknown/unknown";
}
header("Content-disposition: inline; filename=" . $attachmentinfo['filename']);
header("Content-type: $header");

if ($isimage)
{
    // watermark options:
    $filename = "watermark.png"; // use a PNG-24 to preserve transparency!

    $im = imagecreatefromstring($attachmentinfo['filedata']);
    imagealphablending($im, true);

    $watermark = imagecreatefrompng($filename);

    $y = imagesy($im) - imagesy($watermark);

    $w = imagesx($watermark);
    $h = imagesy($watermark);

    imagecopy($im, $watermark, 0, $y, 0, 0, $w, $h);

    imagejpeg($im, "", 80);
}
else echo $attachmentinfo['filename']; 


and i still get the red x's for images.

Yep, exactly. I'm going to try upgrading to 2.3.0 and see how it works then...

[S.Shady]

works fine but none of my attachments of images fully gets uploaded it seams

[007]

Ok I just upgraded to 2.3.0 and still nothing.

(Yes I do have GD2 and I have it selected in the options..)

[filburt1]

What exactly happens when you go to an attachment directly?

[matthepepe]

you get a red x.

[Courage]

I have attachments as files hack installed

Instead of

PHP Code:

header("Content-disposition: inline; filename=$attachmentinfo[filename]");
header("Content-Length: ".strlen($attachmentinfo[filedata])); 


I have:

PHP Code:

header("Content-disposition: inline; filename=$attachmentinfo[filename]");
header("Content-Length: $filesize"); // attachments as files hack 


I deleted header("Content-Length: $filesize"); , but I think that now i can add files without size limit checking ...

Ideeas ?

[007]

Yeah I now have 2.3.0 and I still have a red X. I contacted my host again to see if I really do have GD2.0+ and they said I do...

[Skyline_GT]

How come I have this line

header("Content-disposition: inline; filename=$attachmentinfo[filename]");

instead of

header("Content-disposition:$attachment filename=$attachmentinfo[filename]");

Where the heck does a fella FIND a good copy of gd2 for Red Splat ?? I want to use this hack, as well as watermark the pix outa the gallery (photopost), but I can't seem to locate a decent RPM for red splat 7.1 and 7.3.

Any Ideas any one ? All I can find wants tons of pre 6.2 rpm's installed as dependencies..
