Should I send nudes for my gfs birthday?

I (18f) posted about this yesterday (or maybe the day before, it's gone midnight so IDK).

I wasn't sure what to send my gf (also 18f) for her birthday and ruled out basically everything but a card:
Chocolate/candy/flowers/jewellery - she has dogs and if they get at it then... yikes
Some sort of grand romantic gesture or keepsake - we agreed to keep it subtle until she's out of her parent's house
Actual visit - too expensive, right in the middle of freshers week and we promised to visit a few weeks later, anyway
Cute video - her best friend beat me to it, and I helped her make it

She's said she'd like a card, and she doesn't want me to spend anything. We haven't had sx yet, and I'm planning on visiting her about a month after her birthday, during the October half term.
If I got her a regular sized card, and then I took some (tasteful) photos with me in lingerie or something and put it in a smaller envelope inside the card, do you think that would that work?
