Econa plugin images for k2 in control panel

 Hello!
I found one flaw in using the Econa k2 plugin. I want to know how to fix it

On the K2 itemlist page in control panel used native k2 images (md5)
If I delete native images from the server I'm lose images in the control panel.
Tell me please how to display the Econa plugin images in control panel
By default, the following code is in the control panel:

<?php if(JFile::exists(JPATH_SITE.DS.'media'.DS.'k2'.DS.'items'.DS.'cache'.DS.md5("Image".$row->id).'_XL.jpg')): ?>
                                <a href="https://www.firecoders.com/<?php echo JURI::root(true).'/media/k2/items/cache/'.md5("Image".$row->id).'_XL.jpg'; ?>" title="<?php echo JText::_('K2_PREVIEW_IMAGE'); ?>"     class="modal">
                                <?php if(K2_JVERSION == '30'): ?>
                                <img src="https://www.firecoders.com/<?php echo JURI::root(true).'/media/k2/items/cache/'.md5("Image".$row->id).'_M.jpg'; ?>" />
                                <?php else: ?>
                                <?php /*<img src="https://www.firecoders.com/templates/<?php echo $this->template; ?>/images/menu/icon-16-media.png" alt="<?php echo JText::_('K2_PREVIEW_IMAGE'); ?>" />                 */ ?>
                                <?php endif; ?>
                                </a>
                                <?php endif; ?>

What code should I use to display econa's images? Thank you

why? econa k2 plugin have option "Keep native images" and checkbox "yes" or "no".
I want use only econa's images for save disk space.

Please tell me how can I use the images of econa in the K2 control panel? how do I print an econa image instead of

<img src="https://www.firecoders.com/<?php echo JURI:: root (true).'/media/k2/items/cache/'.md5 ("Image".$row - >id).'_M.jpg' ?> > "

I'm sorry
But this code does not work!
The first part I added immediately before defined

('_ JEXEC') or die;

The second part inside loop.
I do not know php very well and
Maybe I did something wrong.

Could you correct my code to reflect your edits?

Could you give me a full fragent code?
I'm using K 2.8

Now I have

<?php if(JFile::exists(JPATH_SITE.'/media/k2/items/cache/'.md5("Image".$row->id).'_XL.jpg')): ?>
<a href="https://www.firecoders.com/<?php echo JURI::root(true).'/media/k2/items/cache/'.md5("Image".$row->id).'_XL.jpg'; ?>" title="<?php echo JText::_('K2_PREVIEW_IMAGE'); ?>" data-fancybox="gallery" data-caption="<b><?php echo $row->title; ?></b> - <?php echo JText::_('K2_PUBLISHED_IN'); ?> <b><?php echo $row->category; ?></b> <?php echo JText::_('K2_BY'); ?> <b><?php echo $row->author; ?></b>">
<?php if(K2_JVERSION == '30'): ?>
<img src="https://www.firecoders.com/<?php echo JURI::root(true).'/media/k2/items/cache/'.md5("Image".$row->id).'_M.jpg'; ?>" />
<?php else: ?>
<img src="https://www.firecoders.com/templates/<?php echo $this->template; ?>/images/menu/icon-16-media.png" alt="<?php echo JText::_('K2_PREVIEW_IMAGE'); ?>" />
<?php endif; ?>
</a>
<?php endif; ?>

Thank you!

If this code can not work, then maybe there is an alternative?

Replace forcibly <img src="https://www.firecoders.com/<? Php echo JURI :: root (true). '/ Media / k2 / items / cache /'. Md5 (" Image ". $ Row-> id) .'_ M.jpg '; ?> "/> to the code that will output from the image database Econa plugin

I use plugin xtlink item k2.
The plugin makes it possible to add similar elements to articles k2.
I was able to display Econa images in this plugin in the front end.
I used the code:

if ($item_params->get('XTlinkedItemImage', 0))
							{
		// Get current image information
        $image = JTable::getInstance('Image', 'EconaK2Table');
        $image->load(array(
            'resourceId' => $XTlinkedItem->id,
            'resourceType' => 'com_k2.item',
        ));
								$imgi = JPATH_SITE .
									'/media/k2/items/cache/' .
									md5("Image" . $XTlinkedItem->id) . '_' .
									$item_params->get('XTlinkedItemImageSize') . '.jpg';

								if (JFile::exists($imgi))
								{
									$XTlinkedItem->image = JURI::root() .
										'media/k2/items/cache/' .
										$image->filename .
										'_' . $item_params->get('XTlinkedItemImageSize') .
										'.jpg';
								}
							}

But I can not get Econa images in the standard admin panel
Help please
Any solution is suitable
