Thank you for your reply, it made me realize I was taking the wrong approach and not asking the right question.
Ultimately, my goal is to have an icon image (in this case a favicon) align with and appear before the post title. Every time I create a new post I need the ability to drop the img src url (into a widget? custom field?) and have the icon spit out.
What is the best approach towards this functionally? I can’t discern the most optimal between custom widget or custom field. I’m definitely too novice.
Appreciate you taking my questions.
