Images and Connector functions

I created new Connector to SQL db. I’m testing different functionalities like selecting and displaying in Interactive table, data filtering, updating etc.

So far all looks good when using Connector function to SQL db.

I have few questions regarding images:

What is best way to store, display and update images when using connector function. It looks like that Tulip image data type is actually URL. Is this correct?

So image datatype in SQL db is actually varchar - table must store URL of actual image when uploaded thru Tulip app?

Can Tulip app use varbinary (where image is stored in db) thru connector function and display it on step?

Thank you,
