Looking for a bit of advice

I have maybe a weird question and need a bit of advice. The other day I got a Ravelry notification that someone making one of my designs had added a photo. I was super excited because it seems that a lot of the people purchasing my patterns don’t really use Ravelry to keep track of projects. I went to look at the photos, which show the lovely beginnings of a project but the knitting chart is clearly visible in two photos.

My heart immediately sank. My first thought was how to go about asking her to crop her photos or blur out the chart. But I’ve let it stew in my brain too long and now I’m not sure what to do. Knitting patterns are my primary income source, and I’d like to believe most people wouldn’t take her photos and try and use the chart, but I know some might – I probably would.

Is there a kind way to go about bringing this to her attention? It’s probably not an intentional thing, and they are lovely snapshots of her work. I would hate upset this person or lose business from people using her image in place of a purchased pattern. Or is this not a big deal at all?
