What does a girl mean when she reply a guy that his facebook pictures are nothing to write home about?

I recently met a guy on facebook and I admired her beauty. I told her if we can hang out on new year day, but she say that my facebook pictures is nothing to write home about.
What does that mean? Is she rude or she's trying to act as a big girl.

NB: I don't often upload pictures on facebook, but I have some decent pictures of myself on facebook
