Answers.Text: Thanks Robin, that's extremely detailed, so I appreciate the effort you've put in. However, I didn't realise that I'd need to create a plugin for it. Seems a lot to do for a load more button. So I'll need to continue to investigate if there's any simpler options maybe via javascript instead.

Answers.Text: of course you can use that too, but this is not an answer to your question. You don't lazy load  your images, you just hide them. It`s up to you but for example I have limited traffic so I would not visit your page if I have to download 40+ images every time even if I don't even want to see them (that's the reason for ajax calls to load content dynamically). 
  The page will take much more time to load if you have (let's say) 80 images per call instead of only 10

Answers.Text: I agree and will definitely try to implement the better way in future, but in this case, I've got no time, and it's just some headshots, so only will be a few hundred kilobytes, and so will solve the immediate issue at least. And then I can work in the background to do it the better way once I have a bit more time.

  ### Answer by username_1 on 2017-10-21. Score: 2 | Accepted answer
  
  Your `block.headshots` is not an array of all images, you have to understand what craft does in order to work properly with it.
  
  `block.headshots` and all other relations (Matrix elements, images, category links...) are all `elementCriteriaModels` so instead of having an array of objects - your `block.headshots` is just a single object that has an iterator interface.
  
  So when you execute `{% for headshot in block.headshots %}` it performs the `.find()` function and returns an array.
  Unfortunately I'm not on my computer currently so I can't provide the exact code so maybe the syntax of something of the following might be wrong, but if you know how to search entries with `craft.entries.find()` [click](https://craftcms.com/classreference/models/ElementCriteriaModel#find-detail) you can correct it, here you have more examples [elementCriteriaModel](https://craftcms.com/docs/templating/elementcriteriamodel). Your code should look like
  
  `{% for headshot in block.headshots.find({limit: 10}) %}`
  
  It does not matter if you are searching pages (entries), assets, matrix blocks, sections, categories or whatever.. Craft does always the same, building an elementCriteriaModel that is executed as soon as you loop through it.
  
  edit: your controller to load the assets could look like this
  
  ```
  public function actionLoadAssets(){
      $this->requireAjaxRequest();
      $response = array(
          'success'   => false,
          'message'   => ''
      );
  
      // config how many entries should be loaded
      $config = craft()->globals->getSetByHandle('config');
      $limit = $config['countReloadImages'];
      // offset.. how many did we load already
      $offset = craft()->request->getPost('offset');
      // which block is it
      $matrixIndex = craft()->request->getPost('matrixIndex');
      // entryId
      $entryId = craft()->request->getPost('entryId');
  
      if($entry = craft()->elements->getElementById($entryId)){
          // search for the correct field -> we just insert an offset
          // this is untested, maybe you have to play around with the correct number
          // I'm not sure if you can just send the id of the matrixfield and use 'id' => $matrixIndex
          // you could to try it out...
          $matrix = $entry->team->find([
              'offset'    => $matrixIndex
          ]);
          $html = '';
          if($matrix && ($assets = $matrix->headshot->find(['offset' => $offset, 'limit' => $limit]))){
              // build a template to render the images, you'll return the html
              $html = $this->renderTemplate('some tempalte here', array(
                  'asset' => $assets
              ));
          }
          // you could include your logic if you found less entries than configured ($limit) and return a "hide reload button"
          $response['html'] = $html;
          $response['success'] = true;
      }else{
          $response['message'] = Craft::t('could not find entry with Id ' . $entryId);
      }
  
      return $response;
  }
  
  ```
  
  Edit2: I found a better solution:
  
  ```
  public function actionLoadMore(){
      $criteria = craft()->elements->getCriteria(ElementType::Asset);
      // id of your field headtshot
      $field = craft()->fields->getFieldById(5);
  
      $criteria->relatedTo = array(
          'sourceElement' => //your matrix ID,
          'field'         => $field->id
      );
      $criteria->offset = //your offset;
      $criteria->limit = //your limit;
      $assets = $criteria->find();
  
      // render template -> return html look at the first example
  }
  
  ```
