Image Field in Custom Module

In the Contacts module I can add an image and it displays. If I create a custom module based on contacts and add in the photo field ( same steps as contact module) the image does not display. It comes up as a broken image. Is there something else I need to do to get this to work. I would also like to display the image in listview.

it’s my case. i don’t have any solution for this. Please help us!
