Can't post image file into given directory with $_FILES function - php

Question

I have two pretty much similar cases of adding image files to directory and they both work, but I don't know why this one doesn't, since it's done on the same principles.
And since it's not pasting into the "show" directory, the output is following:
add-album.php
<?php
include "config.php";
if (isset($_POST["submit_album"])) {
$album = $_POST["album_name"];
$album_prikazna = $_POST["album_prikazna"];
$photo = $_FILES["album_prikazna"]["album_name"];
$upload = "show/".$photo;
$add_album = $conn->query("INSERT INTO gallery_albums (album_name, album_prikazna) VALUES ('$album', '$album_prikazna')");
move_uploaded_file($_FILES['album_prikazna']['album_name'], $upload);
header("Location: fotogalerije.php?add_album_action=successfull");
}
?>
fotogalerije.php
<div class="container">

<form method="post" action="add-album.php">

<input type="text" name="album_name" /> <input type="submit" name="submit_album" value="Add" /><br>
<input type="file" class="mt-3" name="album_prikazna">

<?php
if (isset($_GET["add_album_action"])) {
if ($_GET["add_album_action"] == "successfull") { ?>

<?php }
}
?>
<div class="">
<?php
$albums = $conn->query("SELECT * FROM gallery_albums");
while ($album_data = $albums->fetch_assoc()) {
$photos = $conn->query("SELECT * FROM gallery_photos WHERE album_id = ".$album_data["album_id"]."");
?>
<div class="p-0 m-0">
<img src="<?php echo $album_data['album_prikazna']; ?>" width="125" class="p-1" />
<a href="view-album.php?album_id=<?php echo $album_data["album_id"] ?>">
<?php echo $album_data["album_name"];
$imagePrikazna = $album_data["album_prikazna"];
?>
(<?php echo $photos->num_rows; ?>)</a>
<?php }
?>
