上传文件到服务器问题

I'm trying to upload and save file in dir called images through a form. Form looks like this:

<form name="spremi" action="spremaj.php" method="post" enctype="multipart/form-data">
<input type="file" id="file" name="image" />
<input type="submit" value="Send" name="send" />
</form>

And php script looks like this:

if (file_exists("images/" . $_FILES["file"]["name"]))
  {
    echo $_FILES["file"]["name"] . " already exists. ";
  }
else
  {
    move_uploaded_file($_FILES["file"]["tmp_name"],"images/" . $_FILES["file"]["name"]);
    echo "Stored in: " . "images/" . $_FILES["file"]["name"];
  }

Script always prints message "already exists". I know that questions like this were already asked, but none of the answers helped me. This code didn't work either on localhost, or web server. Thank you.

In your html form you do not have a file parameter so your php needs to accept image so change

if (file_exists("images/" . $_FILES["image"]["name"]))
{
   echo $_FILES["image"]["name"] . " already exists. ";
}else
  move_uploaded_file($_FILES["file"]["tmp_name"],"images/" . $_FILES["file"]["name"]);

to

if (file_exists("images/" . $_FILES["image"]["name"]))
{
   echo $_FILES["image"]["name"] . " already exists. ";
}else
   move_uploaded_file($_FILES["image"]["tmp_name"],"images/" . $_FILES["image"]["name"]);
