addslashes() don't properly work.
Before use it, need add this:
       $str_any=str_replace("\\","\\\\",$str_any);
and only then:
       $str_any=addslashes($str_any);

Please post a short example to show what goes wrong and why.

$image_file=fopen($HTTP_POST_FILES['imagefile']['tmp_name'],"rb");
unset($upload);
while(!feof($image_file)) $upload.=fread($image_file,65535);
fclose($image_file);
$upload=str_replace("\\","\\\\",$upload);
$upload=addslashes($upload);
$query_str="INSERT INTO images (id, image_type, image) VALUES('', '".$HTTP_POST_FILES['imagefile']['type']."', '$upload')";
$insert=mysql_query($query_str, $link);

Function addslashes don't add slashes '\' before '\', and result is corrupt image.

addslashes() works fine for me on binary data...
Unlikely to be a bug: ask support questions on the appropriate mailinglist (see http://www.php.net/support.php).
