Take screenshot alternative

Hey Guys

I have to download a picture which is present in a web portal , that image differs each time , its size varies each time , but it is present is same web portal

i tried take screenshot but its nt working , please tell me alternative , i cant use http request because its present in a secure web portal

Please tell solution

we would recommend to check if HTTP request will work when Authentication info will also be used for the call.

A bad way would be as an alternate an UiAutomation of right click save image as action

i tried by giving credentials in simple http section of http request its givng success response of login page but after that the particular page iam unable to download pic

Buenos dias, amigo me gustaria saber si lograste resolver tu dificultad ya que tengo una similar, quedo atento.
gracias
