To take a photo with a foreign friend, you can say "Can we take a picture together?" or "Can we get a photo?" in Engpsh. You can also say "Can I have a photo with you?" if you would pke to be in the photo with your foreign friend.

Alternatively, you can also say "Can we take a selfie?" if you want to take a photo of yourselves using a camera or smartphone.

For example, you can say "Can we take a picture together? I want to show my family back home." or "Can we get a photo? I'd pke to add it to my album."

I hope this helps! Let me know if you have any other questions.
