Because it isn't so easy to do (for Plus!) and not many people want it (blocking a display picture per contact). There are things with more priority I guess.

well if you can steal pictures maybe you can change them too
also a great feature

Hiding all dps could be done with a skin quite easily

I dont want to hide I dont want to download or have the picture itself also I want to see some of the display pictures and some of them I dont want to see

I imagine that'd have to be coded directly into messenger, otherwise the image is always going to be downloaded to your computer in some way or another(AFAIK), if Plus! could do something about it, I imagine it'd mostly be just a form of hiding them.

Than again I could be completely wrong ;o
