hi,

i actually found a suloution to this. I basically used the nivo slider (http://nivo.dev7studios.com/) which seemed reliable and extendable.

What i did was use the image galleri already there, ( i had simple image galleri PRO installed), and set the thumbs to be bigger. 

in the file jw_sigpro.php in the plugins/content/ folder i removed everything inside $headIncludes on line 115.

then on line 177 in the same document i removed everyting inside $html_template and replaced it with     

<img src="{THUMB IMAGE FILEPATH}" title=""/>


What i like about nivo slider is that is dosn't require anything other than the <img> tag.


on k2 i did following:

in the item.php file in my template (components/com_k2/templates/)

i placed the following code where i wanted my gallery slider. This way the first main image will always be first.

 <?php if($this->item->params->get('itemImage') && !empty($this->item->image)): ?>
      
    
    <?php // Item Image ?>
      <div class="itemImageBlock">
           <?php if($this->item->params->get('itemImageGallery') && !empty($this->item->gallery)): ?>
              <div id="slider">
                  <img src="<?php echo $this->item->image; ?>" alt="<?php if(!empty($this->item->image_caption)) echo $this->item->image_caption; else echo $this->item->title; ?>" style="width:<?php echo $this->item->imageWidth; ?>px; height:auto;" />
            
            <?php echo $this->item->gallery; ?>
          </div>
        <?php else:    ?>
        <img src="<?php echo $this->item->image; ?>" alt="<?php if(!empty($this->item->image_caption)) echo $this->item->image_caption; else echo $this->item->title; ?>" style="width:<?php echo $this->item->imageWidth; ?>px; height:auto;" />
    
      <?php endif; ?>



The code for the nivo slider javascript (in attition to the nivo slider main javascript and jquery of course):

<script type="text/javascript">
$(window).load(function() {
	$('#slider').nivoSlider({
		manualAdvance:true,
		controlNav:true,
		keyboardNav:true,
		effect:'fade',
		slices:1,
		
	});
	
});
</script>



Did it for me.
