timthumb not finding image

I'm building a site using wordpress installed on localhost.

For some reason my post.php page is not displaying post thumbnails (featured images). I have identified that it is a problem with timthumb.php which is not correctly locating the image url. I have searched for hours online and tried a number of solutions but nothing seems to be working.

The basic problem is I think in this line in my blog.php file:

<?php
if ( has_post_thumbnail() ) { ?>
    <a href="<?php the_permalink() ?>"><img class="postimg" src="<?php bloginfo('stylesheet_directory'); ?>/timthumb.php?src=<?php get_image_url(); ?>&amp;h=200&amp;w=470&amp;zc=1" alt=""/></a>
<?php }

else { ?>
    <a href="<?php the_permalink() ?>"><img class="postimg" src="<?php bloginfo('template_directory'); ?>/images/dummy.png" alt="" /></a>
<?php } ?>

My functions.php script defines get_image_url as follws:

function get_image_url(){
    $image_id = get_post_thumbnail_id();
    $image_url = wp_get_attachment_image_src($image_id,'large');
    $image_url = $image_url[0];
    echo $image_url;
    }

In the site it returns the dummy.png image (broken image) - when I right click the image and open in a new tab the error I get is:

"A Timthumb Error has occurred - Cannot find the internal image that you specified"

It then shows my query string:

Query String : src=http://localhost/wordpress/frouzeh/wp-content/uploads/sites/3/2013/04/PurpleNecklace.png&h=200&w=470&zc=1

however if I actually go to the image using the URL:

http://localhost/wordpress/frouzeh/wp-content/uploads/sites/3/2013/04/PurpleNecklace.png

the image show up fine

  • I am developing on windows using the local host so it can't be a permission control for the folders
  • Using the latest version of timthumb 2.8.11
  • I have tried removing the resizing parameters: &h=200&w=470&zc=1 from the file but still get the same error

  • I have enabled (as some solutions suggest in the timthumb.php file):

    define ('ALLOW_ALL_EXTERNAL_SITES', TRUE);

  • There is no tilde in my site name as other solutions suggest.

I'm really at a loss here. And would appreciate any help - seems like it may be a simple syntax error or something but I can't find it.

Solution

  • After trying to fix this for hours, I decided to move my wordpress site to a live server (linux). I then changed the access permissions to the Cache folder to 755 and my images came back.

    This was a permission problem, however I am still unsure why it wouldn't work on my windows machine even after going through properties of the cache folder and changing the permissions there - any insight would be appreciated...
