This is a very simple image viewer that runs in the web browser. It uses a single .html file and 36 lines of code. Save the code as index.html - clicking on this file will open a window in your browser allowing you to choose an image from your pc to display. I've been able to open a 1024 x 1024 image - nice.
Here's the code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Simple Image Viewer</title>
<style>
body {
background-color: #f0f0f0;
text-align: center;
font-family: Arial, sans-serif;
}
img {
max-width: 100%;
height: auto;
border: 2px solid #000;
margin-top: 20px;
}
</style>
</head>
<body>
<h1>Simple Image Viewer</h1>
<input type="file" id="fileInput" accept="image/*">
<img id="imageViewer" src="#" alt="Your image will appear here.">
<script>
const fileInput = document.getElementById('fileInput');
const imageViewer = document.getElementById('imageViewer');
fileInput.addEventListener('change', function() {
const file = this.files[0];
const url = URL.createObjectURL(file);
imageViewer.src = url;
});
</script>
</body>
</html>
