Why didn't the American long press come out and remain in the mobile phone prompt?

I'd like to ask if the pictures of American English pop up and are saved on my mobile phone. Because the author or publisher of the picture has set permissions, saving is prohibited.

If you read other people's beautiful essays and find the picture you want to collect, you can capture the picture directly by screen capture, and then cut off the border with the editing function of your mobile phone, so that you can collect this beautiful picture completely.

American English is widely used: travelers share their travels in American English, record their scenery with photos, and record their journeys with words, which are vivid and interesting. Photographers use it to share their own works, match their own experiences and explanations of each work, and have deeper communication with colleagues. It is more convenient for staff to write reports, share them with the department's WeChat group or send them directly to leaders than PPT.
