Tomthumb script not working on Heartinternet Servers

After my last blog Slider Images not Showing on Responsive Creative Wordpress Theme  I've realised that this may because of a wider issue that is due to the Tomthumb script not working on Heart Internet servers.  ( although I'm not 100% sure of this fact )  . 

My issue this time is with the Gallery I'm using on the theme Midway Responsive and the specific issue is with the thumbnails showing .

This theme uses timthumb.php  to do the reduction; I also tried the plugin 'thumbGen' but that produced no success either.

No I noticed that in the 'uploads' folder I already had different sized images made of the images I was trying to show.  So I've written a function to call up one of those smaller sizes and will change the width inside the 'img' tag. 

here's my changes

OPEN

wp-content/themes/midway/template-gallery.php

FIND

echo themex_thumbnail($post->ID,460,intval($height));

REPLACE WITH

echo lrip_gallery_thumbnail($post->ID);

SAVE


OPEN

wp-content/themes/midway/framework/functions.php




AT THE BOTTOM OF THE PAGE BEFORE THE ? >  ADD


// Gallery Thumbnail issue ( heart related ) hack

function lrip_gallery_thumbnail($ID){
    global $blog_id;
    $src = wp_get_attachment_url( get_post_thumbnail_id($ID) );
// going to explode using .jpg and fix on a new ending
    $img_url_array = explode('.jpg', $src);
    $img_url = $img_url_array[0].'-300x225.jpg';
    return $img_url;
}


SAVE AND UPLOAD
