image upload

[hannes]

I have a problem with uploading images and creating thumbs from it.

Not all the time, but sometimes, the full size image is completely
uploaded and correct, while the thumbnail only builds a vertical part
of the real image... the rest is grey..

How is that possible? Uploading is not the problem, but resizing
somehow is i guess.

Please help me,

Hannes

Hi Hannes,

Check line 134 in your sourcecode of the script that handles the
resizing....

How do you expect us to answer such a question based on the information we
receive?

Haha.. sorry..
well, i thought maybe someone recognises this problem. Why can this
image be grey at the bottom? Maybe you've seen this before and you can
tell me what i should be thinking about?

IMHO you should be thinking about providing more information :)

The code would be a good place to start, as well as your PHP version,
what web server you have, what file formats you're allowing, how much
memory you have in your server AND have allocated to PHP..

Basically ANY information would be helpful.

this is my code where something goes wrong:
$handle = fopen($tmpHolde r, "rb"); // opent 'temp/tmp.img'
echo $handle;
$contents = fread($handle, filesize($tmpHo lder));

if($original = imagecreatefrom string($content s)){
}
else{
// nog een keer
if($original = imagecreatefrom string($content s)){
}
else{
exit("mislukt, probeer het opnieuw<BR>");
}
}
$source = imagecreatefrom string($content s);
$original_width = imagesx($origin al);
$original_heigh t = imagesy($origin al);

if($original_wi dth < $formaatSmall){
$newwidth = $original_width ;
$newheight = $original_heigh t;
}else{


$percent = ($original_heig ht/$original_width );
if($original_wi dth>$original_h eight){
//horizontaal
//percent < 1
$newwidth = $formaatSmall;
$newheight = $formaatSmall*$ percent;
}
else if($original_wi dth<$original_h eight){
//verticaal
//percent 1
$newwidth = $formaatSmall/$percent;
$newheight = $formaatSmall;
}
else if($original_wi dth=$original_h eight){
//vierkant
//percent = 1
$newwidth = $formaatSmall;
$newheight = $formaatSmall;

}
}
$thumb = imagecreatetrue color($newwidth , $newheight);

if (!imagecopyresi zed($thumb, $source, 0, 0, 0, 0, $newwidth,
$newheight, $original_width , $original_heigh t)){
exit("aanmaken van thumbnail mislukt<BR>");
}

$thumbnail = $folder_small."/".$form_bestand snaam;

if(!is_file($th umbnail)){
$handle2 = fopen($thumbnai l,'x');
chmod($thumbnai l, 0777);
fclose($handle2 );
}
imagejpeg ($thumb, $thumbnail, 60);

fclose($handle) ;
