Why does the same picture link open and display differently on different devices?

when I was using a rich text editor, I uploaded a web picture and randomly found one on Baidu ( https://image.baidu.com/).

but when uploading, I saw that the address of the image in the data uploaded to the background is a little different ( & has been globally replaced with & ). Directly copy the src link of the a tag in the rich text content, and open another image (coded, but it still looks dirty). I display the content of rich text in react ( dangerouslySetInnerHTML ), and the picture is fine.

later I found several pictures on Baidu and replaced & globally with & , all showing the dirty picture.

remove all the forehead parameters behind the picture on Baidu, that is, the soiled picture

this is the link https://timgsa.baidu.com/timg?image=

the other two different pictures are displayed on Android and ios. Why?
