I would like to ask js multi-picture upload how Filter has chosen the picture?

I would like to ask js how to upload multiple pictures which have been selected by Filter?
I"m going to get the original name of the uploaded picture, and then match it with the name of the currently uploaded picture, but all I get is the name of the currently uploaded picture, and I only get one name if I select multiple pictures.

isn't FileReader able to convert a picture to Base64? compare whether the base64 of the newly added image is the same as the previous one (I'm not sure that the base64 generated by the same picture twice is different, it should be the same in theory)
