I was reading their delivery terms and they say that they will take a picture of the parcel when it's dropped off, as proof of delivery

Photographic evidence Is useless and can easily be circumvented.

If (for example) the package Is left at the doorstep and a photo Is taken, It's left unattended, hence anything could've happened to It In your absence - which essentially means you did not personally receive It.
