preview image in browser object URLs
View preview-image-in-browser.html
<!-- The following code uses object URLs, which is much more efficient than data URL for viewing large images (A data URL is a huge string containing all of the file data, whereas an object URL, is just a short string referencing the file data in-memory):

<!-- java script only -->
<html>
<img id="blah" alt="your image" width="100" height="100" />
<input type="file" onchange="document.getElementById('blah').src = window.URL.createObjectURL(this.files[0])">
</html>
