liasuzuki on "[Theme: Customizr] Featured image thumbnails showing up in posts, but not in pages"

Hi,

I tweaked my content.php file with this:

<p style="float:right; margin:10px; border:3px solid lightgrey"><?php if(is_single() || is_page())
if ( has_post_thumbnail() ) {
the_post_thumbnail('medium');
}
echo '';
?></p>

Now my thumbnails are showing up on my posts exactly as I want. How do I now get them to do the same on my pages?

Page example: http://aksb.org/about/instructor/chris-ziliotto-teaching-apprentice/

Thanks!

Lia
