Adding member data with images to a CMS collection

Question:
I’m migrating a wordpress site to Wix and we have a database of 700 members to bring into the Wix CMS. How do you upload hundreds of image files as well as data (such as name and email) to a dataset? More details below.

Product:
Wix CMS

What are you trying to achieve:
Bring a database of 700 members into the Wix CMS that includes image files.

What have you already tried:
The database includes the member name, email, etc.— but it also includes a photo of each member. I can upload all the content except the photos by using a CSV file. I can’t upload images from a CSV file unless the images are links.

Does anyone know how to bring in a database of people into a Wix CMS collection that includes images?

Thank you so much.
