<?php foreach ($data[0] as $film):?>
<div class = <?= $film['id_film'] ?> >
<div class= "col-lg-3 col-md-4 col-xs-6 thumb filmDiv" >
<a class="thumbnail " id = "filmShow" href= <?= "/project/admin/showFilm/" . $film['id_film']?>>

Your problem is that the path to the image in the database is stored as local path from your machine (D:/uwamp/www/project/upload/tcf_animal17.jpg), where for it to display correctly it needs to be a path relative to the root of your web server documents.
For example, if your web server document root is D:/uwamp/www, then the path of the image you need to store should be project/upload/tcf_animal17.jpg.
Of course if you can't get the image to be stored within the web root, then you always have an option to just dump the content directly, however it's really not a good idea, for performance reasons:
<?php
$mime = image_type_to_mime_type(exif_imagetype(string $image_path));
$data = "data:$mime;base64," . base64_encode(file_get_contents($image_path)); ?>
?>
<img src="<?= $data ?>">
This code is very crude and does no error checking - you'll need to add that for a production-level application.
