Hi vgutierrez2012
Yes, you can achieve that by overriding the category blog view a bit.
Kindly check if your site already overrode the category blog view in template or not:
/templates/t4_blank/html/com_content/category/blog_item.j3.php
If not yet, you can copy this file from base folder of T4 plugin:
/plugins/system/t4/themes/base/html/com_content/category/blog_item.j3.php
and paste into the template folder: /templates/t4_blank/html/com_content/category/
Then open this new file:
/templates/t4_blank/html/com_content/category/blog_item.j3.php
At approx line 26:
<?php echo LayoutHelper::render('joomla.content.intro_image', $this->item); ?>
change it to:
<?php echo LayoutHelper::render('joomla.content.full_image', $this->item); ?>
I also assume that you're using latest version of T4 plugin 🙂
