How can I load images from port 80 to port 8100?

My app is running on localhost:8100, but the images that I’m trying to load are on localhost:80.

I have a local website, the info is loaded into a local database, into one of the tables there are the names of the images, until here, everything is okay, but now, on the app side I create a service to consume the info but I only can see the name of the image not the image as well.

What I’m doing wrong or what can I do?
