How to download and display an image from the web

[JERisBRISK]

I recently figured out how to download and display an image in DearPyGui for an NFT collection browser I'm coding up. I posted this image in the DPG Discord and someone asked me how I did it.

Some discussion ensued, and I was asked to post my answers here. First, I used the following articles as inspiration:
https://github.com/hoffstadt/DearPyGui/wiki/Drawing-API
https://stackoverflow.com/questions/13137817/how-to-download-image-using-requests

Then, I wrote the following routine:

import requests
import shutil
import dearpygui.dearpygui as dpg
import dearpygui.logger as dpg_logger
...
logger = dpg_logger.mvLogger()
...
def DownloadImage(url, destination):
    logger.log(f"Downloading {url}")
    response = requests.get(url, stream=True)
    if response and response.status_code == 200:
        with open(destination, 'wb') as out_file:
            response.raw.decode_content = True
            shutil.copyfileobj(response.raw, out_file)
        del response
        logger.log(f"{destination} downloaded.")
    else:
        logger.log_error(f"response: {response}")

Later in my code, I optionally download and add the image thumbnail to my table via this bit:

if not exists(thumbFileName):
    DownloadImage(thumbUrl, thumbFileName)

if exists(thumbFileName):
    logger.log(f"Thumbnail {thumbFileName} is in the cache.")
    w, h, _, data = dpg.load_image(thumbFileName)
    with dpg.texture_registry():
        thumbnail = dpg.add_static_texture(w, h, data)

# add the thumbnail
if exists(thumbFileName):
    dpg.add_image(thumbnail, label=name, parent=table)

The code could do a bit more to avoid redundant I/O (like checking if the thumbnail static texture exists instead of checking for the file being present on disk), but this pretty much is the gist of it.
