Sort listings by price questions

I’ve used the instructions here – https://wpgeodirectory.com/how-to-sort-listings-by-price/ and have been able to successfully sort listings for my three packages. I have two related queries though…

1) This works for the GD category/listings pages but I’m using the [gd_listings] shortcode and it doesn’t work. How do I get it to work when using the short code please?

2) I have a free package where no images are allowed. Currently it shows a blank placeholder in the listings for free listings but I don’t want this to display so that the title/description is aligned to the left. I achieved this previously using featured listings and the following:

.gd-post-featured .geodir-post-img {display:block !important;}
.geodir_category_list_view li .geodir-post-img {display: none;}

I can’t use that now as only one of the three packages are set as featured for use in a slider elsewhere on the site. So, is there a way to hide images based on the package ID? Or any other way to achieve what i want?

Thanks
