Is there any way to put a banner inside every single post, for example in the upper right corner ?
Of course to be visible only in single post and not in the main page.

I'm trying it inside the template settings but i can't figure it out if its possible.

Any help please ?

See how it's done for the icon for sticky posts at Theme Options -> Post/Page Styling -> POST Container: STICKY and do something similar for POST Container

That's exactly what i'm looking for Flynn thank you. But i have a small problem cause the banner is actually a script and i can't figure it out how to put it like the sticky.gif

You could put the code into one of the Kicker textareas at Post / Page Info Items and adjust the position with CSS. Otherwise you'd have to put it into index.php after <div class="post-bodycopy"> with conditional comments

<?php if ( is_single() ) { ?>
<div class="mycode">
...
</div>
<?php } ?>

CSS Insert

div.mycode {
float: right;
margin: ...
padding: ...
}

Or, if you plan to do more edits for single post pages, make a copy of index.php as single.php. Then you'd not need the <?php if ( is_single() ) { ?> and <?php } ?> parts

Many thanks! The index.php solution worked fine!

Are there any changes at 3.3.3, for the index.php solution ?

In 3.3.3 put it above

<?php bfa_post_bodycopy(); // Post Bodycopy: To edit the output, see functions/bfa_post_parts.php ?>

Thanks again Flynn. Now it's working again

Is this working in 3.4 ?

Found it!

For the rest, you have to do the same actions but the code must be copied at :
Style & Edit CENTER COLUMN --> The LOOP
