Images are now less customizable? Can not get to stretch or select!

Question:
Has the utility of images changed?? I can’t seem to find the image in the layers tab as it doesn’t show and the only way i can interact with it is through the side panel (see pic).

I want to blow the picture/ image up to 150% of the page so it stretches and covers white margins but that function has seem to of disappeared??

Any one know why this has happened? Thank you
