Ads / Content between/inside the post

Between posts you could modify your theme to place your advert block inside the <?php while (have_posts()) : the_post(); ?> loop (which ends with <?php endwhile; ?>.

Under images could be more tricky. You may need to use a plugin to do that, as you would probably be filtering the_content

Yes, so is there any such plugin that does the job ? or any plugin similar to it so that I can check how it works and maybe I’ll get it this working ?

You might need to write your own plugin. Or something like this maybe?

Your best bet is probably a google search.

i would like to include 5 similar posts, using Similar Posts plugin, inside the text of each single post in my blog. i use the theme mimbo3. it renders posts with <div class=”entry clearfloat”>
<?php the_content(‘<p>’.__(‘Read the rest of this entry’,’Mimbo’).’»</p>’); ?>

<?php wp_link_pages(array(
‘before’ => ‘<p> ‘.__(‘Pages:’,’Mimbo’).’ ‘,
‘after’ => ‘</p>’,
‘next_or_number’ => ‘number’));
?>
</div>

where should and how should i include the related plugin tag <?php similar_posts(); ?> to keep the similar posts titles in a box inside the text?
