For the wall

Hand one over.

Anyone can send a picture. It does not go straight up - it waits where only he can see it, and he decides what hangs on the wall. If it goes up, it goes up with your name on it.

Paste your picture here

Copy a picture from anywhere - a page, a screenshot, your phone - then click this box and press Ctrl+V. You can drag one in as well. No link needed, and it never goes to some other website.

Three pictures an hour each. Nothing is published by sending it, and nothing about you is stored beyond the name you typed.
