Help needed with grid layout and images

Hi Guys,

How do I go about making it a grid layout and having the store logo as the image instead of the discount text?

See screenshot 1- this is sept theme I am using. I’d like it to be screenshot 2

This code doesnt seem to display the images above:
<div class=”row wlt_search_results grid_style” >
<?php echo do_shortcode(‘[LISTINGS dataonly=1 show=12 custom=”new”]’); ?>
</div>

Is there something else that needs done?

Cheers
