请教下各位tkinter怎么用for循环显示图片？

Question

由于用for循环界面只会显示一张图，很是气人。
下面的代码是想要显示的4张图，如果用for的话，怎样可以方便的写出并且实现效果？
如果直接这样，

    image_size=(150,150)
    fm1=tk.Frame(window)
    files=['candy.jpg','mosaic.jpg','rain-princess.jpg','udnie.jpg']
    for file in files:
        img1 = Image.open(f'./images/style-images/{file}')
        img1 = img1.resize(image_size, Image.ANTIALIAS)
        img1 = ImageTk.PhotoImage(img1)
        tk.Label(fm1, image=img1).pack(side=tk.RIGHT, padx=10)

其效果是这样的：

目前我四个图片都显示，就用下面的代码，copy了四次，但是怎么直接用for来写呢？

    image_size=(150,150)
    fm1=tk.Frame(window)
    files=['candy.jpg','mosaic.jpg','rain-princess.jpg','udnie.jpg']

    img1 = Image.open(f'./images/style-images/{files[0]}')
    img1 = img1.resize(image_size, Image.ANTIALIAS)
    img1 = ImageTk.PhotoImage(img1)
    tk.Label(fm1, image=img1).pack(side=tk.RIGHT,padx=10)

    img2 = Image.open(f'./images/style-images/{files[1]}')
    img2 = img2.resize(image_size, Image.ANTIALIAS)
    img2 = ImageTk.PhotoImage(img2)
    tk.Label(fm1, image=img2).pack(side=tk.RIGHT, padx=10)

    img3 = Image.open(f'./images/style-images/{files[2]}')
    img3 = img3.resize(image_size, Image.ANTIALIAS)
    img3 = ImageTk.PhotoImage(img3)
    tk.Label(fm1, image=img3).pack(side=tk.RIGHT, padx=10)

    img = Image.open(f'./images/style-images/{files[3]}')
    img = img.resize(image_size, Image.ANTIALIAS)
    img = ImageTk.PhotoImage(img)
    tk.Label(fm1, image=img).pack(side=tk.RIGHT, padx=10)

    fm1.pack()

这样写，多家一个img_list保留img对象。

image_size=(150,150)

img_list=[]
fm1=tk.Frame(window)
files=['candy.jpg','mosaic.jpg','rain-princess.jpg','udnie.jpg']
for file in files:
    img1 = Image.open(f'./images/style-images/{file}')
    img1 = img1.resize(image_size, Image.ANTIALIAS)
    img1 = ImageTk.PhotoImage(img1)
    img_list.append(img1)
    tk.Label(fm1, image=img1).pack(side=tk.RIGHT,padx=10)


fm1.pack()
