Image Rendering Problem

Here's the rundown of the problem that I'm having:

I have a page that I am rendering that has multiple icons being displayed. The icons are being stored as binary files in the database. When I load the page with a collection of items (icons) to be displayed, not all of the icons are being displayed. In fact, the icons which actually get displayed seem a bit random.

From the main html file, a partial is called for each of the items:

    <% if @new_items -%>       <ol>         <li><%= render :partial => 'shared/item', :collection => @new_items, :spacer_template => 'shared/li' %></li>       </ol>     <% end -%>

Inside the partial, each image is rendered with the following code:

    <img src="<%= url_for(:action => 'get_icon', :id => %>" alt="Unable to Display" class="uas-app-icon-link"/>

The get_icon method is just a function which contains the following:

    def get_icon         item = ItemDocument.find(:all, :conditions => ["item_id == ? AND                                                        id == (SELECT icon_id                                                               FROM items                                                               WHERE id == ?)",                                                        params[:id], params[:id]])         icon = item[0]         send_data(icon.file,                         :type => icon.content_type, :disposition => "inline")     end

Anyways, only some of that actual images are actually rendered when the page is complete. I checked to see whether the urls exist for each image, and all of the image urls are fine; they render just as they should. I have tried using both WEBrick and Mongrel in my server configuration of the localhost. WEBrick is a bit better, but both of them still fail to some extent. The server log for WEBrick is the following:

    Processing ApplicationController#get_icon (for at 2009-09-01 15:45:05) [GET]       Parameters: {"id"=>"2"}

Currently I am using sqlite3 v3.6.17 (gem) and rails v2.3.3 if that helps any. I did try making a quick temporary project that did the same kind of rendering with send_data and an iterating partial call, and it has the same behavior. I tried using both sqlite and mysql v5.0.85 (v2.8.1 gem), and the results were the same. Any help at this point would be greatly appreciated. I am a beginner just to let you know, just FYI for those who might be able to help out. Thanks in advance.
