I use the following code for uploading a picture and displaying it on the website:
<p><input type="file" accept="image/*" name="image" id="file" onchange="loadFile(event)" style="display: none;"></p>
<p><label for="file" style="cursor: pointer;">Upload Image</label></p>
<p><img id="output"/></p>
<script>
var loadFile = function(event) {
var image = document.getElementById('output');
image.src = URL.createObjectURL(event.target.files[0]);
console.log(image.clientHeight)
};
</script>
As you can see, I´m trying to find the width and height of that image. How can be this done? I was trying using both image.width / image.clientWidth but none of them worked, it always returned 0 only (or undefined).
