I'm creating a app to build smart cards to post on instagram.
The idea is simple: 1) insert a url; 2) get a open graph from url; 3) generate card from htmlcsstoimage.com.
Looks like this:
But in some cases, the open graph image is not ok or not exists. In this cases, i want to insert a file upload, like in image.
But how can i change the image to construct a query for htmlcsstoimage?
Some like a temporary upload, or in retool storage? How can i select what image is to use? Like a radio button or a select button: "open graph image" and "file upload image"?
