err – she wants to alter a picture of her B&B to advertise the business??
I think the term is ‘tidy up’, not ‘alter’. I used to do this sort of thing all the time, especially with skies, where someone had taken a photo on an overcast day, so the sky was just white, so I’d select the sky, and looking through my collection of skies, find one that most closely matched angle of light, etc, drop it in and resize, etc. Just makes the scene as a whole look more cheerful. I’d clean up water marks, or rust stains from old metal work, too.
Just makes a building look a little tidier, is all. Not mis-representing it.
