Really having trouble getting Thumbnail Images to Show with U-Design theme..

Hi, any help would be superb… been on this half a day now.

url: exhilarateme.com

This is the code I place in a text file for setting up latest post to appear:

[udesign_recent_posts title="Recent Posts" category_id="9" num_posts="2" post_offset="0" num_words_limit="23" show_date_author="0" show_more_link="0" show_thumbs="1" thumb_frame_shadow="1" post_thumb_width="100" post_thumb_height="80"]

I’ve set up a custom field in posts as – post_image – and that now makes a posts image appear in the category archives pages but getting thumb to show is not happening – just directs to default thumb.

I know nothing about coding but guessing I need to mess around with a php file.

Like i said,. any help would be fantastic, thanks.
