I have to provide a responsive website targeting Opera Mini devices. I have to make the page's size as small as possible. As Opera Mini uses a proxy to compress page's size, I was wondering if Opera Mini does load hidden elements (like pictures) on the client device if the elements are specified as follows:
<img style="display:none" source="..."/>
Opera Turbo does compress images to decrease overall page size. But it does not remove any markup from the code. Furthermore, the compression mechanism can be disabled in the settings (at least in Opera Mobile).
