Bug description: Upload of Image damages the image
Description:
------------
If i upload an jpg-file and save the stream to disk my jpg is damaged
after this. If i view the "source" of the jpg i can see that the html-form
data is appended. "Content-Disposition: form-data; name="userpic";
filename="66_automotive_102x72_1305008.jpg" Content-Type: image/jpeg". The
size of the file i doubled.
If i set an directive in the apache config like
"ForceType image/jpg" and upload again the jpg isn´t damaged.
Reproduce code:
---------------
Upload Source:
<?php
$original = $_FILES['userpic']['tmp_name'];
$filename = $_FILES['userpic']['name'];
if ($original != '') {
copy($_FILES["userpic"]["tmp_name"], "./tmp/".$filename);
$filename= "./tmp/".$filename;
print "<img src=".$filename.">";
$handle = fopen ($original, "rb");
$contents = fread ($handle, filesize ($original));
$len = strlen($contents);
$pos = strpos($contents, 'Type:');
#print "<BR>";
#print "<BR>";
print $contents."<BR>";
fclose ($handle);
exit;
}
?>
<FORM enctype="multipart/form-data" method="post">
<TABLE>
<TR><TD>
<INPUT type='file' name='userpic' /><input name='weilhalt'
type='hidden'
value='wert'><INPUT type='hidden' name='target_input'
value="seite_teaser"
/></TD>
<TD align='right'><INPUT type='submit' name='confirm'
class='button'
value='hochladen' /><BR></TD></TR>
</TABLE>
</form>
Expected result:
----------------
A normal upload.
Actual result:
--------------
