Here's a tip, using CSS with media restrictions you can trick it to show your own supplied logo from the website.
There is obviously a chance that this will change when opera is requesting the page using a different resolution than 1024 x 756 and a minimal change a random person opens the website using that exact resolution.
@media screen and (min-width: 1024px) and (max-width: 1024px) and (min-height: 756px) and (max-height: 756px) {
body {
background: #fff url(<url to your image>) center center no-repeat !important;
}
body * {
display: none;
}
}
