How to create a single slideshow combining several image fields?
&lt;?php if ( ($image_slide == 'true') ): ?&gt;
        &lt;div class="image-post-slider"&gt;
              &lt;ul&gt;
                &lt;?php while ($img_count &lt; $counter) { ?&gt;
                  &lt;li&gt;
                          &lt;div class="preloader"&gt;
                                &lt;a class="bwWrapper single-image link-icon" href="&lt;?php print $node_url; ?&gt;"&gt;
                                    &lt;img src="&lt;?php echo file_create_url($node-&gt;field_image['und'][$img_count]['uri']); ?&gt;" alt="" &gt;
                                &lt;/a&gt;                        
                            &lt;/div&gt;
                  &lt;/li&gt;
                  &lt;?php $img_count++; } ?&gt;      
              &lt;/ul&gt;
        &lt;/div&gt;    
        &lt;?php endif; ?&gt;


Put something like above snippet in your node.tpl.php
This will create links of images and their links if any. Then apply normal css/js to make it in slideshow
