问题
I've implemented a bootstrap carousel with thumbnails on my website but the thumbnail size is off, they are way too small.
I fiddled some with the CSS code within the foto_new page. But my knowledge of CSS is not enough to get this working.
Here is my page code:
<head>
<title>Reis Foto"s</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="css/lo.css">
<link rel="stylesheet" href="css/boots.css" crossorigin="anonymous">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" >
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>
<style>
/* Make the image fully responsive */
.carousel-inner img {
width: 100%;
height: 100%;
}
#myCarousel .list-inline {
white-space:nowrap;
overflow-x:auto;
}
#myCarousel .carousel-indicators {
position: static;
left: initial;
width: initial;
margin-left: initial;
}
#myCarousel .carousel-indicators > li {
<!--width: initial;-->
<!--height: initial;-->
width: 200px;
height: 50px;
text-indent: initial;
}
<!--#myCarousel .carousel-indicators li img {-->
<!--display: block;-->
<!--opacity: 0.5;-->
<!--}-->
#myCarousel .carousel-indicators li.active img {
opacity: 1;
}
#myCarousel .carousel-indicators li:hover img {
opacity: 0.75;
}
</style>
</head>
<body>
<div class="container">
<div class="row">
<!--Ik gebruik hieronder alleen het middiv omdat dat de enige info is die ik wil vervangen-->
<div class="col-md-12" id="middiv" style="background-color: rgba(255, 255, 255, 0.1)">
<div id="myCarousel" class="carousel slide" data-ride="carousel" align="center">
<!-- Wrapper for slides -->
<div class="carousel-inner">
<div class="carousel-item active">
<img src="/fotos/auto.jpg" alt="Los Angeles" style="width:80%;">
</div>
<div class="carousel-item">
<img src="/fotos/robot.jpg" alt="Chicago" style="width:80%;">
</div>
<div class="carousel-item">
<img src="/fotos/vrachtwagen.jpg" alt="New york" style="width:80%;">
</div>
</div>
<!-- Left and right controls -->
<a class="carousel-control-prev" href="#myCarousel" data-slide="prev">
<span class="carousel-control-prev-icon"></span>
</a>
<a class="carousel-control-next" href="#myCarousel" data-slide="next">
<span class="carousel-control-next-icon"></span>
</a>
<!-- Indicators -->
<ol class="carousel-indicators list-inline">
<li class="list-inline-item active">
<a id="carousel-selector-0" class="selected" data-slide-to="0" data-target="#myCarousel">
<img src="/fotos/auto.jpg" class="img-fluid">
</a>
</li>
<li class="list-inline-item">
<a id="carousel-selector-1" data-slide-to="1" data-target="#myCarousel">
<img src="/fotos/robot.jpg" class="img-fluid">
</a>
</li>
<li class="list-inline-item">
<a id="carousel-selector-2" data-slide-to="2" data-target="#myCarousel">
<img src="/fotos/vrachtwagen.jpg" class="img-fluid">
</a>
</li>
</ol>
</div>
</div>
</div>
</div>
</body>
</html>I expect that the thumbnails are a bigger size.

Not sure how this will play with the rest of your CSS.
/* Make the image fully responsive */
.carousel-inner img {
width: 100%;
height: 100%;
}
#myCarousel .carousel-indicators {
position: static;
margin-top:20px;
}
#myCarousel .carousel-indicators > li {
width:100px;
}
#myCarousel .carousel-indicators li img {
display: block;
opacity: 0.5;
}
#myCarousel .carousel-indicators li.active img {
opacity: 1;
}
#myCarousel .carousel-indicators li:hover img {
opacity: 0.75;

</div>It does look like it is response, and you can change the thumbnail sizes with the:
#myCarousel .carousel-indicators > li {
width:100px;
}
There is some issues with the popper.js loading, which is why it is commented out.
There is a Fiddle: Demo
