Sorry for a late reply, yes it should be ok in functions.php of the theme.

Another thing, the theme should be enable/support the featured image/post_thumbnail. To do this, you can use something like this: add_theme_support('post-thumbnails');

To automatically add the 1st image in the post as a featured images, you need to customised it a little bit. Since the code just for assign an image as a featured image/post thumbnail for the post. Probably by hook into post save.

You can put it into your theme functions.php.

Hi jojimori,

This really a late reply but since I’m also had encountered such problem(automatically add images as featured images of the post). For a several days I try to get the solution and do some research in internet. Lastly I found the below solution(where the code is from this codex documentation page. I just make it as a function and added the last line for making it as a featured images.

Hopefully this will help other, remember the $post_id is the parent post ID(where the image been attach) and the $filename is the absolute path of the image files

function set_featured_image($post_id,$filename) {
	$wp_filetype = wp_check_filetype(basename($filename), null );
	$attachment = array(
		'post_mime_type' => $wp_filetype['type'],
		'post_title' => preg_replace('/\.[^.]+$/', '', basename($filename)),
		'post_content' => '',
		'post_status' => 'inherit'
	);
	$attach_id = wp_insert_attachment( $attachment, $filename, $post_id );
	// you must first include the image.php file
	// for the function wp_generate_attachment_metadata() to work
	require_once(ABSPATH . "wp-admin" . '/includes/image.php');
	$attach_data = wp_generate_attachment_metadata( $attach_id, $filename );
	if (wp_update_attachment_metadata( $attach_id,  $attach_data )) {
		// set as featured image
		return update_post_meta($post_id, '_thumbnail_id', $attach_id);
	}
}

thanks alchymyth, actually the problem already solved where I checked the sidebar in sidebar.php like you said the logic in header the sidebar are not activated yet ?? so I believe it was my fault…
Anyay thank for correcting me and point the problem ??

cheers

If you want to replace the icon then simply replace the images/link-rss.gif to your own image. However, if you want to make a series of different icons, then you can copy the .rss a { … } and give it a different name such as .rss2, .rss-socialicon etc. Then copy/change the background:url(images/link-rss.gif) no-repeat 0 0; to other icon image such as background:url(images/link-socialicon.gif) no-repeat 0 0;
After that find below line(not sure where the author place it-might be in your header.php or other pages)
<span class=”rss”>….</span> and add a new one based on thats. For example: <span class=”socialicon”>….</span>
