little picture is black

$time = time();
if ($file1_name != "") {
mkdir ("members/uploads/$time", 0777);
copy("$file1", "members/uploads/$time/$file1_name");
$pic = $url."/members/uploads/".$time."/".$file1_name;

$img_data=getimagesize($file1); 
$src_w=$img_data[0]; 
$src_h=$img_data[1];
$picklein=imagecreate(75,75); 
imagecopyresized($picklein,$file1, 0, 0, 0, 0, 75, 75, $src_w, $src_h);
chdir ("members/uploads/$time/");
header("Content-type: JPEG"); 
ImageJPEG($picklein,"thumb_".$file1_name);
copy("$picklein", "members/uploads/$time/$picklein");
$picklein = $url."/members/uploads/".$time."/thumb_".$file1_name;

This make from the picture file1 a little picture thump_file1 and save it. But the thump_file1 is just a black picture. What is wrong with my code?

Try using imagecolorallocate(). The first color you allocate after imagecreate() will become your background color.

$bg = imagecolorallocate ($picklein, 255, 255, 255);

This should give you a white BG

now is my little picture white.

I need a resize of the 'pic' in 'picklein'. How do I do that.

Her is my code:

$time = time();
if ($file1_name != "") {
mkdir ("members/uploads/$time", 0777);
copy("$file1", "members/uploads/$time/$file1_name");
$pic = $url."/members/uploads/".$time."/".$file1_name;

$img_data=getimagesize($file1); 
$src_w=$img_data[0]; 
$src_h=$img_data[1];
$picklein=imagecreate(75,75); 
$bg = imagecolorallocate ($picklein, 255, 255, 255); 
imagecopyresized($picklein,$file1, 0, 0, 0, 0, 75, 75, $src_w, $src_h);
chdir ("members/uploads/$time/");
header("Content-type: JPEG"); 
ImageJPEG($picklein,"thumb_".$file1_name);
copy("$picklein", "members/uploads/$time/$picklein");
$picklein = $url."/members/uploads/".$time."/thumb_".$file1_name;
}

Use imagecopyreszed() the way you already are, just specify a different size than the original image. Right now, you are resizing it to 75x75 which is the same size that image is originally.
