Hello, does the teacher not delete the corresponding pictures when deleting the data? Also, are there no examples of uploading multiple images here?
It doesn’t matter. You can delete it or not. It doesn’t take up much space. For multi-image uploading, you can learn about the uploader multi-image upload plug-in. You don’t need to write it yourself.
