How about writing a function that replaces the following:
<img src="image.jpg" width="300px" height="400px" />
with this:
<div style="width: 300px; height: 400px; background: url('image.jpg');"></div>
Then maybe you can call the function:
<?php place_image( 'image.jpg' ); ?>
To return the second code example.
Technically, users can still download the image, but they’d have to inspect the code, and manually navigate to the image file. I came across this notion while trying to find ways to present photos in a responsive design.
