Hi folks,
I'm trying to use the subsample method in the PhotoImage class to resize an image I have in a list that links to a Label widget in Tkinter but python says there is no such method. I know I could use Image.resize before calling Photoimage but since I'd like to resize the image at any time I don't know what to do once it's been converted to PhotoImage. Could someone please show me what I'm doing wrong? I'm relatively new to Tkinter and very new to PIL...Thanks...

for i in imgs:
image=Image.open(i)
photo=ImageTk.PhotoImage(image)
self.list.append(photo)
def resize(self,num,fact):
self.list[num]=self.list[num].subsample(fact)
#image=image.resize((50,100),Image.ANTIALIAS)
#photo=ImageTk.PhotoImage(image)
#photo.subsample(2,2)
#self.list[num]=photo
