Can't get Copilot to reimagine uploaded pic

My facebook is flooded with Co-Pilot adds showing reimagined photos based on an original pic. The ads show a before and after. I wanted to try that and on both my windows desktop and IOS phone, it never reimagines the uploaded photo. If I ask it "to reimagine image as a pixar movie poster", then it spits out Pixar movie posters without a hint of the uploaded image.  What am I doing wrong?
