Thumbnails wont show up in a category?

I think it’s an easier way to show thumbnails (for categories and so on).
I’m trying to show a thumbnail in every post or excerpt but I’m a php beginner so I’ve decided to do this: I’ve uploaded a thumbnail folder.
I want to show a thumbnail named “the post id” + jpg (or gif or so on).
Does anybody know what should I do for getting it?

Thanks a lot in advance !

@s7orm is your archive page calling the_excerpt()? if so that strips out all formatting and html from the content.

To both: There is a brilliant plugin: advanced excerpt that will let you add images and lots of other stuff.

An alternative would be to call the image from the post seperately and display it along side the text:

Add this to your functions.php (or make it if you don’t have one):

<?php
function get_post_image($num) {
global $more;
$more = 1;
$link = get_permalink();
$content = get_the_content();
$count = substr_count($content, '<img');
$start = 0;
for($i=1;$i<=$count;$i++) {
$imgBeg = strpos($content, '<img', $start);
$post = substr($content, $imgBeg);
$imgEnd = strpos($post, '>');
$postOutput = substr($post, 0, $imgEnd+1);
$postOutput = preg_replace('/width="([0-9]*)" height="([0-9]*)"/', '',$postOutput);;
$image[$i] = $postOutput;
$start=$imgEnd+1;
}
if(stristr($image[$num],'<img')) { echo '<a href="'.$link.'">'.$image[$num]."</a>"; }
$more = 0;
}
?>

then put <?php get_post_image('1'); ?> where you want the image to appear.

This code will make a link out of the image that will take the user to your post. You can then style the image in css to get the right height and width etc.

<?php get_header(); ?>
<?php 	$blog_cat = html_entity_decode(get_option('T_blog_cat'));

Thats my archive.php , so no it doesnt call the_excerpt
any ideas?

Thanks,
s7orm

This is only calling in the title when you are on an archive page. It looks like your image is coming in through a plugin called “Get the image“. If you don’t have that plugin that might be the root of the problem ??

i dont have any plugin thats getting the image, so how would i remove this ?

anyone?
and also, i tried to add the ‘Get the image’ plugin, and when i went to activate it, it said

Fatal error: Cannot redeclare get_the_image() (previously declared in /homepages/33/d325106976/htdocs/wp-content/themes/workaholic/images.php:43) in /homepages/33/d325106976/htdocs/wp-content/plugins/get-the-image/get-the-image.php on line 43

Heres my images.php code,

If not we can do it another way, but let’s try this first!
