Pics on twitter don't show in feed


Hi. How are you? I was looking everywhere in Google but I didn’t find solution. My pics on the twitter don’t appear in tweets like a preview. And pics gone from all previous posts. It’s strange because if someone retweet my pics they appear normal. The same if I’ll retweet back my pic. What can I do? What is the reason of this issue. I found some answers but they are not logic.
