Having rocks larger than your turtle's head would ensure s/he wouldn't be able to swallow them. That said, my RES has had some of the same rocks in his tank for about 3 years now and some of them are definitely smaller than his head, but still to big for him to actually swallow. He's never sjown the slightest interest in eating them (he spends time spinning some of them around and fluttering at them), and they're nice to look at, so I've just let them be.
The rocks in the picture don't look like your turtle could ingest them, but if you're uncomfortable, maybe you'd feel better taking them out and putting in some larger ones. Or, as RESowner said, take out the smaller ones and leave the rest in, changing them as your turtle grows.
