Hello Theo,

You can remove that link from this file -> JoomlaFolder\components\com_easyblog\themes\default\blog.item.php
LINE 64 until 69

				<!-- Blog Image -->

				<?php if( $row->getImage() && $this->getParam( 'blogimage_frontpage') ){ ?>

					<a href="<?php echo EasyBlogRouter::_('index.php?option=com_easyblog&view=entry&id='.$row->id); ?>" title="<?php echo $this->escape( $row->title );?>" class="blog-image float-l mrm mbm">

						<img src="<?php echo $row->getImage()->getSource( 'frontpage' );?>" alt="<?php echo $this->escape( $row->title );?>" />

					</a>

				<?php } ?>

Replace with

				<!-- Blog Image -->

				<?php if( $row->getImage() && $this->getParam( 'blogimage_frontpage') ){ ?>

					<a href="#" title="<?php echo $this->escape( $row->title );?>" class="blog-image float-l mrm mbm">

						<img src="<?php echo $row->getImage()->getSource( 'frontpage' );?>" alt="<?php echo $this->escape( $row->title );?>" />

					</a>

				<?php } ?>

Hope this help.
