Live photos are downloaded with the wrong extension

[dvdkruk]

First, thanks for building this tool. I think many users would like to back up their Google Photos in original quality, and this might be the way to go.

I played a bit with gphotosdl and found that live photos that normally are downloaded as a zip archive from the web UI are incorrectly named to a picture file format like .jpg, .heic, etc. For example, photos.zip (containing img_123.jpg and img_123.mov) is named to img_123.JPG.

A possible solution is to first check if the file is a zip archive and then unzip it and serve the matching file.

gphotosdl/main.go

Lines 275 to 301 in 8d9e256

	func (g *Gphotos) getID(w http.ResponseWriter, r *http.Request) {
	photoID := r.PathValue("photoID")
	slog.Info("got photo request", "id", photoID)
	path, err := g.Download(photoID)
	if err != nil {
	slog.Error("Download image failed", "id", photoID, "err", err)
	var h httpError
	if errors.As(err, &h) {
	w.WriteHeader(int(h))
	} else {
	w.WriteHeader(http.StatusInternalServerError)
	}
	return
	}
	slog.Info("Downloaded photo", "id", photoID, "path", path)
	// Remove the file after it has been served
	defer func() {
	err := os.Remove(path)
	if err == nil {
	slog.Debug("Removed downloaded photo", "id", photoID, "path", path)
	} else {
	slog.Error("Failed to remove download directory", "id", photoID, "path", path, "err", err)
	}
	}()
	http.ServeFile(w, r, path)
