custom field help

i’m trying to use custom field to retrieve info about img to display in my pages (not in posts).
i have this template

<?php get_header(); ?>

<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
<div id=”content” id=”post-<?php the_ID(); ?>”>

<?php $id = $post->ID; ?>

<?php $img = get_post_meta($id, ‘immagine’); ?>

<img src=”path-to-image-folder/<?php echo $img; ?>.jpg” />

<?php $content = get_the_content(); ?>

<?php echo $content; ?>
</div>
<?php endwhile; endif; ?>

<?php get_footer(); ?>

but what i get is just ( header and footer show fine )

<div id=”content” id=”post-144″>
<img src=”path-to-image-folder/.jpg” />
</div>

i put content both in the page and in the custom field ‘immagine’ but nothing works and the content doesn’t even show.

if i use the_content() insted of get_the_content(); it’s even worse!
all i got is the broken img and this html code!!

<p class=”attachment”><img src=”path-to-image-folder/prk-300×51.jpg” width=”300″ height=”51″ class=”attachment-medium” alt=”” /></p>

i used the EasyPermGals and then i deactivate it (i read somewhere that some plugin use to cache stuff in wp db)

any help? thanks
