Set the max width of an image in tkinter

I know that in CSS you can set the maximum size of an image by using max-width and max-height. I want to do the same thing with tkinter. I've already tried using Image.open("/path/to/file").resize(500), but I got the error TypeError: 'int' object is not iterable. Here is my code:
from tkinter import *
from PIL import Image, ImageTk
root=Tk()
current_image=0
images=[ImageTk.PhotoImage(Image.open("/users/27cadem/documents/display.png").resize(500))]
panel=Label(root,image=images[current_image])
panel.pack()
root.mainloop()

The code can be something like this:
from tkinter import Tk, Label
from PIL import Image, ImageTk
root = Tk()
file = 'img-path.png'
image = Image.open(file)
max_width = 500
pixels_x, pixels_y = tuple([int(max_width/image.size[0] * x) for x in image.size])
img = ImageTk.PhotoImage(image.resize((pixels_x, pixels_y)))
label = Label(root, image=img)
label.image = img
label.pack()
root.mainloop()

Why tkinter shows same image in different widget even images are loaded separately?

First image is for background which is shows 2 times, And second one is a profile image which in not showing, Both photos are present in same root directory and have same format (jpg).
from tkinter import *
from PIL import ImageTk, Image
import json
with open('config.json') as config_data:
data = json.load(config_data)['variables']
root = Tk()
root.title(data['title'])
##TODO: for full screen
# root.wm_attributes('-fullscreen', 'true')
# MAIN BG SECTION:
image = Image.open("bg.jpg")
image = image.resize((1620, 880), Image.ANTIALIAS)
bg_image = ImageTk.PhotoImage(image)
# PHOTO FRAME SECTION:
canvas = Canvas(width=data['canvas_width'], heigh=data['canvas_height'], bg="gray11")
canvas.pack()
canvas.create_image(0, 0, image=bg_image, anchor=NW)
frame_image = Image.open("profile.jpg")
frame_image = image.resize((400, 400), Image.ANTIALIAS)
f_image = ImageTk.PhotoImage(frame_image)
photo_Label = Label(root, image=f_image).pack()
root.mainloop()

As #acw1668 mentioned frame_image = image.resize(...) should be frame_image = frame_image.resize(...)

I Cant get an image to be resized and displayed using tkinter

So im trying to make an app that will display images, and the image I have is 1000*1000 but this is way too big, I need a way to resize the image. I've tried using PIL and ImageTK but that didn't work, here's my code so far:
from tkinter import *
app = Tk()
app.title('embeded image')
fname = Canvas(bg = 'black', height=100, width=100)
fname.pack(side=TOP)
image = PhotoImage('Sun.png')
image = image.resize((25, 25), Image.ANTIALIAS)
icon = fname.create_image(image=image)
fname.pack()
app.mainloop()
I've no idea why this doesn't work, im relatively new to Tkinter so sorry if it's obvious.

You mix two differnt class PhotoImage in tkinter which doesn't have resize and PIL.Image which have resize
import tkinter as tk
from PIL import Image, ImageTk
app = tk.Tk()
fname = tk.Canvas(height=200, width=200)
fname.pack()
pil_image = Image.open('Sun.png')
pil_image = pil_image.resize((25, 25), Image.ANTIALIAS)
image = ImageTk.PhotoImage(pil_image)
icon = fname.create_image((0,0), image=image, anchor='nw')
app.mainloop()

How do I place an image (.png) within a `LabelFrame`, and resize it, in Tkinter?

I'm trying to place a .png image within a LabelFrame in a Tkinter window. I imported PIL so .png image types should be supported (right?). I can't seem to get the image to show up.
Here is my revised code:
import Tkinter
from Tkinter import *
from PIL import Image, ImageTk
root = Tk()
make_frame = LabelFrame(root, text="Sample Image", width=150, height=150)
make_frame.pack()
stim = "image.png"
width = 100
height = 100
stim1 = stim.resize((width, height), Image.ANTIALIAS)
img = ImageTk.PhotoImage(image.open(stim1))
in_frame = Label(make_frame, image = img)
in_frame.pack()
root.mainloop()
With this code, I got an AttributeError that reads: "'str' has no attribute 'resize'"

#Mickey,
You have to call the .resize method on the PIL.Image object and not the filename, which is a string. Also, you may prefer to use PIL.Image.thumbnail instead of PIL.Image.resize, for reasons described clearly here. Your code was close, but this might be what you need:
import Tkinter
from Tkinter import *
from PIL import Image, ImageTk
root = Tk()
make_frame = LabelFrame(root, text="Sample Image", width=100, height=100)
make_frame.pack()
stim_filename = "image.png"
# create the PIL image object:
PIL_image = Image.open(stim_filename)
width = 100
height = 100
# You may prefer to use Image.thumbnail instead
# Set use_resize to False to use Image.thumbnail
use_resize = True
if use_resize:
# Image.resize returns a new PIL.Image of the specified size
PIL_image_small = PIL_image.resize((width,height), Image.ANTIALIAS)
else:
# Image.thumbnail converts the image to a thumbnail, in place
PIL_image_small = PIL_image
PIL_image_small.thumbnail((width,height), Image.ANTIALIAS)
# now create the ImageTk PhotoImage:
img = ImageTk.PhotoImage(PIL_image_small)
in_frame = Label(make_frame, image = img)
in_frame.pack()
root.mainloop()

How to open PIL Image in Tkinter on Canvas

I can't seem to get my PIL Image to work on canvas. Code:
from Tkinter import*
import Image, ImageTk
root = Tk()
root.geometry('1000x1000')
canvas = Canvas(root,width=999,height=999)
canvas.pack()
image = ImageTk.PhotoImage("ball.gif")
imagesprite = canvas.create_image(400,400,image=image)
root.mainloop()
Error:
Traceback (most recent call last):
File "C:/Users/Mark Malkin/Desktop/3d Graphics Testing/afdds.py", line 7, in <module>
image = ImageTk.PhotoImage("ball.gif")
File "C:\Python27\lib\site-packages\PIL\ImageTk.py", line 109, in __init__
mode = Image.getmodebase(mode)
File "C:\Python27\lib\site-packages\PIL\Image.py", line 245, in getmodebase
return ImageMode.getmode(mode).basemode
File "C:\Python27\lib\site-packages\PIL\ImageMode.py", line 50, in getmode
return _modes[mode]
KeyError: 'ball.gif'
I need to use PIL images not PhotoImages because I want to resize my images. Please don't suggest switching to Pygame because I want to use Tkinter.

Try creating a PIL Image first, then using that to create the PhotoImage.
from Tkinter import *
import Image, ImageTk
root = Tk()
root.geometry('1000x1000')
canvas = Canvas(root,width=999,height=999)
canvas.pack()
pilImage = Image.open("ball.gif")
image = ImageTk.PhotoImage(pilImage)
imagesprite = canvas.create_image(400,400,image=image)
root.mainloop()

(An old question, but the answers so far are only half-complete.)
Read the docs:
class PIL.ImageTk.PhotoImage(image=None, size=None, **kw)
image – Either a PIL image, or a mode string. [...]
file – A filename to load the image from (using Image.open(file)).
So in your example, use
image = ImageTk.PhotoImage(file="ball.gif")
or explicitly
image = ImageTk.PhotoImage(Image("ball.gif"))
(And remember – as you did correctly: Keep a reference to the image object in your Python program, otherwise it is garbage-collected before you seee it.)

You can import multiple image formats, and resize with this code. "basewidth" sets the width of your image.
from Tkinter import *
import PIL
from PIL import ImageTk, Image
root=Tk()
image = Image.open("/path/to/your/image.jpg")
canvas=Canvas(root, height=200, width=200)
basewidth = 150
wpercent = (basewidth / float(image.size[0]))
hsize = int((float(image.size[1]) * float(wpercent)))
image = image.resize((basewidth, hsize), PIL.Image.ANTIALIAS)
photo = ImageTk.PhotoImage(image)
item4 = canvas.create_image(100, 80, image=photo)
canvas.pack(side = TOP, expand=True, fill=BOTH)
root.mainloop()

I was banging my head against the wall for a while on this issue until I found the following:
http://effbot.org/pyfaq/why-do-my-tkinter-images-not-appear.htm
Apparently, Python's garbage collector can trash the ImageTk object. I imagine apps using alot of widgets (like mine) are more susceptible to this behavior.
