Featured Image not showing ???

https://codex.www.ads-software.com/Post_Thumbnails

you might need to edit page.php to include the code for a post thumbnail;

<?php the_post_thumbnail(); ?>

what theme are you using?
does the theme’s demo show the featured image being used in pages?

I’m using the default theme Twenty Eleven. The thumbnail image is fine, it’s the larger image that doesn’t display on the top half of the page when viewing that page. What displays is that default sea image where the sea washes up against the somewhat flat rocks.

for a featured image to show in the header, it needs to be at least 1000px wide (unless you have changed the header image dimensions in functions.php)

I looked in that file…I don’t know where I need to make the modification???

around line 120:

'width' => apply_filters( 'twentyeleven_header_image_width', 1000 ),
		'height' => apply_filters( 'twentyeleven_header_image_height', 288 ),

There is no line that like in my functions.php file. Is that the correct file?

I was referring to the code of Twenty Eleven 1.5 – what version of the theme do you have?

if you like, you could paste the full code of functions.php of your theme into a pastebin and post the link to it here – https://codex.www.ads-software.com/Forum_Welcome#Posting_Code

I see. That worked fine. I got to the correct file.

Thanks…
