A few bits of code and boom! Added. 
But why should it be dp? Just something else only those who level can get? Seems a bit unfair especially coming from you as being newbie friendly. I will say this, at least jounin + so that there's not a spam fest of dwelling pics taking up server space.
It's totally possible.
Having it be for DP would hopefully discourage spam; not to mention newcomers need every piece of gold and gem they can keep.
Could we have the ability to put up a dwelling avatar, like shows in the zones, for DP donations? People tend to like to designate their dwellings for rp locations, and it would be cool to say "this is what the location looks like" with a picture.
What would be involved with such a thing?
As Shadow said, it would probably require some coding. Since you said avatar, then presumably how the picture will get up there can be very similar to how we choose avatars in mission HQ. The primary difference, however, would be that this would be hung up in the dwelling instead of the account. This option could be added to the bottom of the dwelling management page, re-using the "choose avatar" page from mission HQ with a few different words (or the same, I don't think it matters too much) and instead redirect the avatar to be displayed in the dwelling rather than the account bio.
Of course, if dwellings don't already have the capacity for pictures, that would need to be added too, but the comment board I presume could just have the zone coding for pictures added to it, except with a space for the uploads or links to control which picture, instead of pulling from a preset group.
I think that is what would be needed for "dwelling avatars", though I could be wrong.
