Show rating on portfolio thumbnail

Hi @shrutigoins, I would recommend to check our custom shortcodes. Here are two relevant topics that would help:

• Can I add a rating inside my WordPress post’s content?
• Is there any PHP shortcodes I can use for my custom posts templates?

Thanks! The first link is what I’ve been trying to use. I’ve been trying to find where exactly the thumbnails are created so hopefully once I find that I can use one of the links you sent.
