I'm back again with my camera app! Trying to overlay/merge two images when saving them.
The error i get is Error: AttributeError: 'PhotoImage' object has no attribute 'load'

There is no load in your code, and you haven't included the entire traceback (which would show where the error is being produced). Is this all the code?

Hello again, I don't see load used directly anywhere it must be called indirectly.
You should show the full error traceback as it indicates where it went wrong and more information.

I think due to Namespace flooding with * imports you've learnt your lesson in why to not do it.
The code is expecting a PIL Image instead I think its got a tkinter Image which has no load method see the tk Image class below.
class Image:

_last_id = 0
def __init__(self, imgtype, name=None, cnf={}, master=None, **kw):
self.name = None
if not master:
master = _get_default_root('create image')

if not name:
Image._last_id += 1
name = "pyimage%r" % (Image._last_id,) # tk itself would use image<x>
if kw and cnf: cnf = _cnfmerge((cnf, kw))
elif kw: cnf = kw
options = ()
for k, v in cnf.items():
if callable(v):
v = self._register(v)
options = options + ('-'+k, v)
self.tk.call(('image', 'create', imgtype, name,) + options)
self.name = name
def __str__(self): return self.name

for k, v in _cnfmerge(kw).items():
if v is not None:
if k[-1] == '_': k = k[:-1]
if callable(v):
v = self._register(v)
res = res + ('-'+k, v)
self.tk.call((self.name, 'config') + res)
config = configure
def height(self):
"""Return the height of the image."""
return self.tk.getint(
self.tk.call('image', 'height', self.name))
def type(self):
"""Return the type of the image, e.g. "photo" or "bitmap"."""
return self.tk.call('image', 'type', self.name)
def width(self):
"""Return the width of the image."""
return self.tk.getint(
self.tk.call('image', 'width', self.name))Try removing from tkinter import * and using import tkinter as tk from now on.

Hi Yoriz!
I tried the above and subsequently had to add tk. before various objects such as Canvas and Button Still getting the same error:

O  I thought that was going to fix it but it's good that you got rid of the * imports 
self.overlay_img = ImageTk.PhotoImage(file=file) self.overlay_img is a Tkinter-compatible photo image
self.photo = ImageTk.PhotoImage(image=Image.fromarray(frame)) self.photo is also a Tkinter-compatible photo image
When calling paste I think the passed in image has to be an actual PIL image.
self.photo.paste(self.overlay_img, (0, 0))
as self.overlay_img is used in the update method You probably need to keep self.overlay_img as it is
def update(self):
...
...
if self.overlay_img:
#self.canvas.tag_raise(self.overlay_img)
self.canvas.create_image(0,0, image=self.overlay_img, anchor=NW)
Here is what I hope will fix it 
When you make self.overlay_img try also making a pill image
def overlay(self):
file = filedialog.askopenfile(
mode='rb', defaultextension='.png',title="Choose Overlay Image", filetypes=[("PNG Files", '*.png')])
if file:
self.overlay_img = ImageTk.PhotoImage(file=file)
self.pil_overlay_img = Image.open(file)Then change
if isTrue and self.overlay_img:
self.photo.paste(self.overlay_img, (0, 0))to
if isTrue and self.pil_overlay_img:
self.photo.paste(self.pil_overlay_img, (0, 0))

This is from the documentation for PIL ImageTk module.
https://pillow.readthedocs.io/en/stable/...ageTk.html
Quote:paste(im, box=None)[source]
Paste a PIL image into the photo image. Note that this can be very slow if the photo image is displayed.
Parameters
im – A PIL image. The size must match the target region. If the mode does not match, the image is converted to the mode of the bitmap image.
box – A 4-tuple defining the left, upper, right, and lower pixel coordinate. See Coordinate System. If None is given instead of a tuple, all of the image is assumed.
Notice that im is a PIL image, not an ImageTk.PhotoImage. You need to load your overlay using Quote:PIL.Image.open(fp, mode='r', formats=None)

Lesson learned on imports 
Unfortunately neither of the above work. I don't get an error but the image saves without the overlay on it.

The error is gone, that's progress 
Try it with both images being pillow images
Paste another image into an image with Python, Pillow
