Element upload file format is not correct, the background refused to receive, how to make the picture not displayed in the photo wall?

the backend does not accept bmp format. Normally, the picture is not displayed. Look at the example on the official website and find out how to deal with it. Has anyone dealt with it? Please tell me the solution, thank you!
