I posted the same question and I have found an answer in the archive. I
guess you are using php on RedHat. The problem is (as Richard sugested)
extra lines that need to be triped off. NOTE: I am not sure if this is
the problem with image files only or this applies to .txt, .doc, etc.
this works for me
---------------------------------------
function fix_php_upload_bug($tmp) {
$infile=fopen($tmp,"r"); // Open the file for the copy
$outfile=fopen("$tmp.new","w"); // create a new temp file
$header=fgets($infile,255); //get the 1st line (netscape sometimes
doesn't add a Content-type line)
//if its more than just a \r\n sequence
then
if (strlen($header)>2)
$header=fgets($infile,255); //get next
line also
while(!feof($infile)) { // Loop through
the remaining file
$temp=fread($infile,128);
fwrite($outfile,$temp,strlen($temp));
//copying contents to new temp file
}
fclose($outfile);
fclose($infile);
copy("$tmp.new","$tmp"); //replace the
original with our new bug fixed file
unlink("$tmp.new"); //and delete the
new file
return filesize($tmp); //return a true
file size
copy($tmp,
"/home/webdesigning/public_html/demo/".$myfile_name);
}
--------------------------------------
Hope this helps
