Using Form, user can submit an image for either the logo or photo or both. Which depends on you configuration of Form. See this page.

Based on you question, I think you want the user to upload the photo. So this should be the shortcode used on the Form page:
[connections photo=TRUE]

Slim Plus defaults to showing the photo, although you could show either. Make sure you shortcode where you inserted the Connections shortcode does not have this in it: image=logo. Although you do not need to set it you could add image=photo.
