How do you add all photos in a folder to an Apple Photos album without importing any pictures?

Question

This is useful when you have a folder of images that may contain images that you already have in your library.

on run
    set folderList to (choose folder with multiple selections allowed)
    
    tell application "Photos"
        activate
        delay 2
    end tell
    
    repeat with baseFolder in folderList
        importFotos(baseFolder, "NEW ALBUM")
    end repeat
end run

on importFotos(aFolder, albumName)
    set imageList to getImageList(aFolder)
    log (albumName)
    if imageList is {} then return
    
    set fotoAlbum to createFotoAlbum(albumName)
    
    repeat with image in imageList
        set fileInfo to info for image
        set filename to name of fileInfo
        set filenameStr to filename as string
        log (filename)
        
        tell application "Photos"
            activate
            set photosImage to search for filenameStr
            add photosImage to fotoAlbum
            log (photosImage)
            
        end tell
        
        
    end repeat
    log (albumName)
