In the picture 了解详情
In the picture 字面意思是“在图片里”，但实际想表达的意思是了解具体情况和事态的来龙去脉。我们通常说 “keep somebody in the picture 使某人了解详情”。请看以下例句。
Jane kept me fully in the picture so I knew what to expect when I attended the meeting.
Please keep me in the picture. I need to know how the project is going.
I'm not really in the picture any more when it comes to the news. I've stopped reading newspapers.
如果说某人 out of the picture，意思就是此人已经与某事不相干了，没有关联了，也不再重要了。
Bob's out of the picture for this job, he's been off sick for weeks.
Sadly she's out of the picture. Her English isn't good enough.
