firebase and list view

Guys I’m having a problem, I’m creating an app that takes photos of the firebase and some information. And I show them all in a list view with an image.
Problem one, it doesn’t load all the images.
Problem two, when I click on the image it is to go to another screen with the image and description but the application closes saying that there was an error.
Note: there are some images that work perfectly and others do not.

what you have done till now?
would you like to send the blocks you have made till now.
