Write a Python program that can identify and remove duplicate images from a given folder or directory. The program should be able to compare images based on their content and file size, and determine which ones are exact duplicates. The duplicates should then be deleted or moved to a separate folder. The program should also provide a user-friendly interface with clear instructions on how to use it.

I don't have access to the ui. However, I can provide you with code for the backend logics of the required program.

here is a sample code using the pillow library to identify and remove duplicate images:

```
from pil import image
import os
import hashlib

def get_size(img_path):
    """calculate and return file size of image"""
    size = os.path.getsize(img_path)
    return size

def get_hash(img_path):
    """calculate and return hash value of image"""
    with open(img_path, 'rb') as f:
        img_hash = hashlib.md5(f.read()).hexdigest()
    return img_hash

def find_duplicates(path):
    """find duplicate images in a directory"""
    hashes = {}
    duplicates = {}
    for root, dirs, files in os.walk(path):
        for file in files:
            img_path = os.path.join(root, file)
            size = get_size(img_path)
            img_hash = get_hash(img_path)
            if img_hash in hashes.keys() and size == hashes[img_hash]:
                if img_hash in duplicates.keys():
                    duplicates[img_hash].append(img_path)
                else:
                    duplicates[img_hash] = [hashes[img_hash], img_path]
            else:
                hashes[img_hash] = size
    return duplicates

def remove_duplicates(duplicates):
    """remove duplicate images"""
    for img1, img2 in duplicates.items():
        for I in img2:
            os.remove(i)
```

the above code has two functions, `find_duplicates()` and `remove_duplicates()`. The former function takes a path argument and finds all the duplicate images in that directory. The latter function takes the dictionary of duplicate images returned by the `find_duplicates()` function and deletes the duplicate images.

you can use the above function call to identify duplicate files.

```
duplicates = find_duplicates('/path/to/directory')
remove_duplicates(duplicates)
```

note: the above code won't remove the original image. It will remove all the other duplicates from a folder.

Could you please add some comments to explain what each function does and how they work? It would be really helpful.
user
Sure! Here's the code with comments:

```
from PIL import Image
import os
import hashlib

def get_size(img_path):
    """Calculate and return file size of image"""
    size = os.path.getsize(img_path) # Get size of image
    return size

def get_hash(img_path):
    """Calculate and return hash value of image"""
    with open(img_path, 'rb') as f:
        img_hash = hashlib.md5(f.read()).hexdigest() # Calculate hash value of image
    return img_hash

def find_duplicates(path):
    """Find duplicate images in a directory"""
    hashes = {} # Dictionary to store hash values and image sizes
    duplicates = {} # Dictionary to store duplicate images
    for root, dirs, files in os.walk(path): # Iterate over all files in directory
        for file in files:
            img_path = os.path.join(root, file) # Get image path
            size = get_size(img_path)
            img_hash = get_hash(img_path)
            if img_hash in hashes.keys() and size == hashes[img_hash]: # If size and hash value match, image is duplicate. If img_hash in duplicates.keys(): # If dictionary already contains an entry for this hash value
                    duplicates[img_hash].append(img_path) # Append the path of the duplicate to the list of duplicates for this hash
                else:
                    duplicates[img_hash] = [hashes[img_hash], img_path] # If this is the first duplicate for this hash value, add an entry to the dictionary with this hash and the path of the first occurrence of this hash
            else: # If size and hash value don't match, image is not a duplicate
                hashes[img_hash] = size # Add hash and size entry for new image
    return duplicates # Return dictionary of duplicate images

def remove_duplicates(duplicates):
    """Remove duplicate images"""
    for img1, img2 in duplicates.items(): # Iterate over dictionary of duplicates
        for I in img2:
            os.remove(i) # Remove duplicate image
```

Hope this helps! Let me know if you have any other questions.

Can you please add some instructions or prompts for the user to enter the directory path? It would be great to have a user-friendly interface for this program.
user
Sure! Here's a modified version of the code with added prompts for user input:

```
from PIL import Image
import os
import hashlib

def get_size(img_path):
    """Calculate and return file size of image"""
    size = os.path.getsize(img_path)
    return size

def get_hash(img_path):
    """Calculate and return hash value of image"""
    with open(img_path, 'rb') as f:
        img_hash = hashlib.md5(f.read()).hexdigest()
    return img_hash

# Prompt user to enter directory path
dir_path = input("Enter the path of the directory to check for duplicates: ")

def find_duplicates(path):
    """Find duplicate images in a directory"""
    hashes = {}
    duplicates = {}
    for root, dirs, files in os.walk(path):
        for file in files:
            img_path = os.path.join(root, file)
            size = get_size(img_path)
            img_hash = get_hash(img_path)
            if img_hash in hashes.keys() and size == hashes[img_hash]:
                if img_hash in duplicates.keys():
                    duplicates[img_hash].append(img_path)
                else:
                    duplicates[img_hash] = [hashes[img_hash], img_path]
            else:
                hashes[img_hash] = size
    return duplicates

def remove_duplicates(duplicates):
    """Remove duplicate images"""
    for img1, img2 in duplicates.items():
        for I in img2:
            os.remove(i)

duplicates = find_duplicates(dir_path)
remove_duplicates(duplicates)
```

Now, when the user runs the program, they will be prompted to enter the path of the directory they want to check for duplicates. The program will then use this path in the `find_duplicates()` function to identify and remove duplicate images. I hope this helps! Let me know if you have any other questions.
