The default option on blog category doesn’t support but you can customize it with my below solution
Open templates/ja_muzic/html/com_content/category/blog_item.php file
From
<?php if (isset($images->image_intro) and !empty($images->image_intro)) : ?>
<?php $imgfloat = (empty($images->float_intro)) ? $params->get('float_intro') : $images->float_intro; ?>
<div class="pull-<?php echo htmlspecialchars($imgfloat); ?> item-image"> <img
<?php if ($images->image_intro_caption):
echo 'class="caption"'.' title="' .htmlspecialchars($images->image_intro_caption) .'"';
endif; ?>
src="<?php echo htmlspecialchars($images->image_intro); ?>" alt="<?php echo htmlspecialchars($images->image_intro_alt); ?>"/> </div>
<?php endif; ?>
Change to
<?php if (isset($images->image_intro) and !empty($images->image_intro)) : ?>
<?php $imgfloat = (empty($images->float_intro)) ? $params->get('float_intro') : $images->float_intro; ?>
<div class="pull-<?php echo htmlspecialchars($imgfloat); ?> item-image"> <a href="<?php echo JRoute::_(ContentHelperRoute::getArticleRoute($this->item->slug, $this->item->catid)); ?>"><img
<?php if ($images->image_intro_caption):
echo 'class="caption"'.' title="' .htmlspecialchars($images->image_intro_caption) .'"';
endif; ?>
src="<?php echo htmlspecialchars($images->image_intro); ?>" alt="<?php echo htmlspecialchars($images->image_intro_alt); ?>"/></a> </div>
<?php endif; ?>
