Your code doesn't do much. Here's what happens when your code runs:

from fpdf import FPDF

import random

import urllib.request





for i in range(1,10):

Here you import your packages and then you start a for loop. The code in the loop will be run once for each loop, and will have access to variable i which will change each time the loop runs.

def image(url):

    ...

The rest of your code consists of a function definition inside a for loop. The function you define can be called image("example.com") but you never do this. So the for loop runs and defines a function many times but never calls it. The function never runs.

Edit: to actually run the code, you could just delete the function definition and supply the URLs directly. The code would run if it wasn't in a function definition.

With the def statement, you are defining a function. It is just building the structure of what that particular piece of code should do. It is not actually executing it.

With the def inside the for loop, you are building the struture again and again, but never actually executing that piece of code.

If you'd insist on using functions, you can define the function outside the loop (once), and then call it using function_name() inside the for loop.

Or, you can eliminate the use of function altogehter, and simply remove the def portion nside the loop, and let the instructions be executed directly.
