Code shows Image in binary in one page but not in other?

[4rxsid]

Hi all,

I've got what appears to me to be some strange behaving code, although I'm sure someone will look at it and inform me....no, here's your issue. I hope 😉

this chunck is part of a 'parent' page and is the page that displays the images' in binary format:

$imgPath = "/home/somesite/public_html/somedir/photos/".$photo;
    $fp = fopen($imgPath, "r");
    $imageFile = fread ($fp, 300000);
    fclose($fp);

$tmpfname = tempnam ("../imagesTMP", "IMG");

$fp = fopen($tmpfname, "w");
fwrite($fp, $imageFile);
fclose($fp);

$photoInfo=GetImageSize($imgPath);

if ($photoInfo[2]=="1") {
    $im_old = imageCreateFromGif($tmpfname);
} elseif ($photoInfo[2]=="2") {
    $im_old = imageCreateFromJpeg($tmpfname);
} elseif ($photoInfo[2]=="3") {
    $im_old = imageCreateFromPng($tmpfname);
}

//**** Delete Temporary File ****
unlink($tmpfname);

$th_max_width = 1.5 * $photoInfo[0];
$th_max_height = 1.5 * $photoInfo[1];

$ratio = ($width > $height) ? $th_max_width/$photoInfo[0] :
$th_max_height/$photoInfo[1];
$th_width = $photoInfo[0] * $ratio;
$th_height = $photoInfo[1] * $ratio;
$im_new = imagecreatetruecolor($th_width,$th_height);
imageAntiAlias($im_new,true);

$th_file_name = $photoDir;
imageCopyResampled($im_new,$im_old,0,0,0,0,$th_width,$th_height,
$photoInfo[0], $photoInfo[1]);

if ($photoInfo[2]=="1") {
    imageGif($im_new,$th_file_name,100);
} elseif ($photoInfo[2]=="2") {
    imageJpeg($im_new,$th_file_name,100);
} elseif ($photoInfo[2]=="3") {
    imagePng($im_new,$th_file_name);
}

//then the image is displayed here with a link
echo "<a href=\"../photos/$photo\" onClick=\"return enlarge('../photos/$photo',event)\"><img name=\"tnImage\" src=\"../photos/$photo\" border=\"0\" alt=\"ENLARGE THIS PHOTO\"></a>";

now, the above code works excellent if i delete it out of the parent page and put it in another page that is opened in a new window (child window) from the parent page.

echo "<a href=\"http://somesite.com/somedir/enlargeTEST.html?photo=$photo\" target=\"enlarge\" onmouseover=\"window.status='ENLARGE THIS PHOTO';return true;\" onmouseout=\"window.status=' ';return true;\" onClick=\"window.open('enlargeTEST.html?photo=$photo', 'enlagre', 'status=yes,menubar=no,scrollbars=yes,height=275,width=300,resizable=no'); return false\"><img src=\"..//../photos/$photo\" border=\"0\" alt=\"ENLARGE THIS PHOTO\"></a>";
//This code works excellent.

So I'm basically just 'enlarging' the image by 1.5x
I want to be able to use the first code because I want to utilize the JS stuff that happens there and not open a new, second window. I know the JS works fine if I cut out the PHP image code stuff. So the JS isn't the issue.

Why would the PHP image code spit out the image in binary in the first example, but work perfectly in the second example (same code, just in a new child window)??

Thanks

Are you referring to the binary getting spit out when you click on the image?

The code samples are different. In the first when you are outputting the html code you are referencing the $photo variable which I am assuming is the uri path to the image file.

Is this file modified at all?

Because in the second code sample you are not referencing the $photo variable in the link but instead calling the php page to provide you with the graphic.

thanks for the reply.

the PHP code is the exact same code that I've used in the 'parent' page, and also in the child page the opens up in a new window. same code, just used in two different pages (not at the same time of course), but with very different results.

so that's the thing the gets me.
