Does JotForm allow me to add a mandatory field that will accept image uploads?

and upload a graphic.  Think a registration for a cutest dog contest where the graphic is an image of their dog.  I have been leaning towards Eventbrite for registration but they will not require a graphic to be uploaded.  It appears Jot Forms will do this.  Is that correct?

We have a File Upload field that allows any file type to be uploaded. You may restrict the file type to images alone as well if needed.

And you're correct - All fields, including the File Upload field, can be set as Required or Not Required.
