As a rule images I add to text messages go through without a problem, but there are a couple people I text where images refuse to post. I have discovered that if they originate a text images will post in my response make it to them . But if I originate the text the image does not post. Neither of them knows why, they are running with default settings and have never, knowingly, blocked images. In fact they tell me they get images from other people, just not from me. That would seem to indicate the problem in on my end, but I have no idea was setting is causing this to happen with on these two people.
