Missing field for database?

[Taisia Auston]

I noticed after reading this article on database fields, I do not have the option for "image" input. Is this a configuration or anything that I'm missing to utilize this field?

I am also missing the image field and cannot add a card cover image due to this.

It's definitely missing from the field type list. I am under the assumption that they haven't implemented this yet as there are a number of features missing at the moment.
