I imagine it'll go against your talk getting into the shortlist.

But there are some conferences that ask and respect your preference whether you'd like the video recording to have your face or just the audio. But I have yet to see a conference that go as far as asking the audience to not take photos of the presenter, so it's pretty much moot if you do not want your photos published at all.

i have seen presenters directly ask the audience to not take pictures. i think it's reasonable request, so i don't think it's a moot point.
