我已经启动并运行了自制的音乐播放器。现在是时候添加一些从当前使用ffmpeg播放的歌曲中提取的专辑艺术作品了。我已经做了很多搜索，但不确定在tkinter中设置这个的最有效方法。粗糙的窗户模型：
+================+
| | Current Artist: Best Band Ever
| (No Artwork) | Current Album: Greatest Album Ever
| | Current Song: Irresistible Tune
| | Play Progress: 99.9 seconds of: 999
+================+
窗口底部有按钮；关闭、暂停、上一个、下一个。
当抓取窗口边框进行放大时，我希望图片的大小最大，因为初始大小是200x200，这很难看到。
我的问题是：如何定义TK标签字段中的图像变量
暂时我已经将图像设置为TK字符串var:
''' Artwork image spanning 4 rows '''
self.current_song_artwork = tk.StringVar()
tk.Label(master2, text="(No Artwork)", font=(None, MON_FONTSIZE))
.grid(row=0, rowspan=4, column=0, sticky=tk.W)
注1:我看过这个问答；A： 如何更新Tkinter标签小部件的图像？使用：
img2 = ImageTk.PhotoImage(Image.open(path2))
panel.configure(image=img2)
panel.image = img2
这似乎是唯一的选择？
注2:首次打开顶层窗口时，不会播放歌曲，也不会显示艺术品的图像。是否需要某种占位符？
注意3：接下来，我想用音乐可视化工具(按比例缩小(、滚动歌词或滚动维基百科上的传记来替换艺术品。因此，用稳健的设计进行未来验证在今天是有意义的。
注意4：这只是我的第二个Python/Tkinter程序，下面的大部分代码都是从第一个程序复制粘贴的。第一个主要是从Stack Overflow复制和粘贴代码。任何关于减少代码行或提高效率的提示都将不胜感激！
TL；DR
完整的(不是很令人兴奋的代码(是：

PID with pgrep ffplay then use kill -s CONT <PID> to resume

首先，这是一个非常全面的问题。这将有助于你和未来的谷歌搜索。
这是可行的，但有几个问题需要注意，即将图像及其外部标签保存到类中。我在这里有一个简单的例子，它将运行、放置和显示标签上的图像。
import tkinter as tk
from PIL import Image,ImageTk
class Player:
def __init__(self):
self.root = tk.Tk()
self.artwork_label = tk.Label()
self.artwork_label.pack()
self.img = ImageTk.PhotoImage(Image.open(path))
self.artwork_label.configure(image=self.img)
path = ...
player = Player()
