var image = document.getElementById('add_image');
image.style.height = '30px';
image.innerHTML = '<div style="margin:5px; width:520px; height:20px;" id="add_images"><input type="file" name="pic" /></div>';
The first half of the function is working, but the second half isn't. I originally tried
style.visibility = 'visible'
but that didn't work so I try innerHTML. Since that didn't work either, I've decided to seek help. Thanks ahead of time.
