I don’t think the full sentence affects anything. I wasn’t trying to make you say something you hadn’t said. I was implying that you didn’t write your sentence properly.
Here’s the original sentence:
Girls dating pictures helps, basically, with boys looking for vanity.
It still says that girls are dating pictures. Or alternatively it could be that “dating” is an adjective modifying “pictures” but I don’t think you meant that either. I think if you would have left out the word “dating” it would have expressed exactly what you meant to say.
Don’t think that I’m a grammar critic; I was just making a joke, until you called me out on it.
