PHP Upload file-type and -size restrictions

Question

ok, so I made this and this works just fine and well:

$file_name = $HTTP_POST_FILES['ufile1']['name'];
$file_name_for_db = ($HTTP_POST_FILES['ufile1']['name']);
$new_file_name = $id."_pic1_".$file_name;
$path = "../users/".$username_session."/photos/".$new_file_name;

if($ufile !=none)
{
    copy($HTTP_POST_FILES['ufile1']['tmp_name'], $path);
    $path_of_pic = "../users/".$username_session."/photos/".$id."_pic1_".$file_name_for_db;
    mysql_query("UPDATE pictures SET pic_1 = '".$path_of_pic."' WHERE id = '$id'");
    header("location:../upload/");
}
else
{
    echo "Error";
}

Now what I've been trying to do is add restrictions.

I've looked through many restriction tutorials, they don't work, always returns error no matter what.

I just want to restric from users uploading anything other than pictures (.png, .jpg, .jpeg, .gif, .bmp) and no more than 5mb

I can do this in HTML, but you can easily get past that. I'm pretty new to programming, so I apologize if the way I write my codes is poor and bulky.

This site has helped me a whole bunch a few times! You guys are awesome! thanks in advance.

this link will help you to restrict images other then .jpg, .jpeg, and so on also the maximum upload size, and if you want to resize the image then also follow the tutorial : http://www.9lessons.info/2009/03/upload-and-resize-image-with-php.html

if( !@imagecreatefromstring(file_get_contents($path))) {
    // (most likely) not an image
}

And:

if( filesize($path) > 5<<20) {
    // image is bigger than 5MB
}

if( !@imagecreatefromstring(file_get_contents($path))) { // (most likely) not an image echo error not an image; } else { upload image } is this the way that would work or vise versa?
