How to add pictures

You will need to do a Post request. For the Body you will need to use form-data with a Key picture and the picture to upload as its Value.

const formData = new FormData();
formData.append("picture", file);
axios.post("http://localhost:3050", formData, {
	headers: { "X-Requested-With": "XMLHttpRequest" },
});
