It comes from:
- 걸다 = to hang something
- -어 두다 = to do something and leave it in that state
So 걸어 두다 means to hang something up and leave it there.
In 벽에 걸어 둔 사진, it describes a photo that someone had hung on the wall and left there. It sounds a bit more deliberate than just saying the photo was hanging.
Because Korean relative clauses come before the noun they describe.
So:
- 벽에 걸어 둔 사진 = the photo that was hung on the wall
- literally, [on the wall hung-and-left] photo
Korean does not need a word like that or which here. The whole verb phrase directly modifies 사진.
-어 두다 adds the idea of:
- doing something in advance
- leaving the result in place
- keeping something in that condition
So 걸어 두다 is not just to hang, but to hang up and leave hanging.
That is why it fits well here: the photo had already been put on the wall before it fell.
