Hi George Marse,
I think that you can edit the theme file in the module.
Example: theme1.php, finding:
<a href="<?php echo $item['link'];?>" target="<?php echo $target;?>" style="color: #1e1690 !important;"><?php echo $readmore_text;?></a>
change to:
<a class="modal" href="<?php echo $item['link'].'&tmpl=component';?>" target="<?php echo $target;?>" style="color: #1e1690 !important; outline: none" rel="{handler: 'iframe', size: {x: 900, y: 450}}"><?php echo $readmore_text;?></a>
-----------
<a href='<?php echo $item['link'];?>' target="<?php echo $target;?>" title="<?php echo $item['title'];?>" style="color:<?php echo $title_so_color?> !important;"><?php echo $item['sub_title'];?></a>
change to:
<a class="modal" href="<?php echo $item['link'].'&tmpl=component';?>" target="<?php echo $target;?>" title="<?php echo $item['title'];?>" style="color:<?php echo $title_so_color?> !important;" rel="{handler: 'iframe', size: {x: 900, y: 450}}"><?php echo $item['sub_title'];?></a>
-----------
<a href='<?php echo $item['link'];?>' title="<?php echo $item['title'];?>" target="<?php echo $target;?>"><?php endif;?><img src="<?php echo $item['thumb'];?>" width="<?php echo $thumb_width;?>px" height="<?php echo $thumb_height;?>px"/><?php if($link_image == 1):?></a>
change to:
<a class="modal" href="<?php echo $item['link'].'&tmpl=component';?>" title="<?php echo $item['title'];?>" target="<?php echo $target;?>" rel="{handler: 'iframe', size: {x: 900, y: 450}}"><?php endif;?><img src="<?php echo $item['thumb'];?>" width="<?php echo $thumb_width;?>px" height="<?php echo $thumb_height;?>px"/><?php if($link_image == 1):?></a>
Thanks
