Hmmm. That made the extra thumbnail and file look prettier but it still isn't showing the Add annotation button. Could it be something on my show.php? This is what I have. Thanks for all your help.
<?php head(array('title' => html_escape($item->title),'bodyid'=>'items','bodyclass' => 'show item')); ?>
<div id="primary">
<h1><?php echo item('Dublin Core', 'Title'); ?></h1>
<?php if (item_has_thumbnail()): ?>
<div class="item-image">
<?php echo display_files_for_item(array('imageSize'=>'fullsize')); ?>
</div>
</div>
<?php endif; ?>
<!-- The following function prints all the the metadata associated with an item: Dublin Core, extra element sets, etc. See http://omeka.org/codex or the examples on items/browse for information on how to print only select metadata fields. -->
<?php echo show_item_metadata(); ?>
<!-- If the item belongs to a collection, the following creates a link to that collection. -->
<?php if ( item_belongs_to_collection() ): ?>
<div id="collection" class="element">
<h3>Collection</h3>
<div class="element-text"><p><?php echo link_to_collection_for_item(); ?></p></div>
</div>
<?php endif; ?>
<!-- The following prints a list of all tags associated with the item -->
<?php if(item_has_tags()): ?>
<div id="item-tags" class="element">
<h3>Tags</h3>
<div class="element-text"><?php echo item_tags_as_string(); ?></div>
</div>
<?php endif;?>
<!-- The following prints a citation for this item. -->
<div id="item-citation" class="element">
<h3>Citation</h3>
<div class="element-text"><?php echo item_citation(); ?></div>
</div>
<!--The following add the ability to add annotations-->
<?php echo image_annotation_display_annotated_image_gallery_for_item();?>
<ul class="item-pagination navigation">
<li id="previous-item" class="previous">
<?php echo link_to_previous_item('Previous Item'); ?>
<li id="next-item" class="next">
<?php echo link_to_next_item('Next Item'); ?>
<?php echo plugin_append_to_items_show(); ?>
</div><!-- end primary -->
<?php foot(); ?>
