You ask me to post this here.
I'm trying to dynamically embed twitter and instagram cards into our blog pages, and have it working, except for the instagram cards showing up still when there is no dynamic link.
You were say we may need some custom code to hide these cards when there is no image link by:
1) Build some check for that natively, or -
2) Find a quick and easy workaround, that can apply to all dynamic items having the condition.
