This is a simple JS script that can efficiently retrieve a random image from Imgur (up to 500) or random Streamable videos (up to 5), using IndexedDB to avoid displaying duplicates.
You can test it here: https://adamcodd.github.io/media-random-generator

Click on the image to view the full size version.
Warning: Some images might be NSFW. All content displayed here belongs to its respective authors.

Thanks to Transformer.js, using only vanilla JavaScript, I'm able to run my quantized ONNX image classification model directly in the browser. Although it's a bit slow, and there are some false positives/negatives due to the quantization, it works effectively.

You can select SFW/NSFW to display only those types of images from random Imgur selections. However, don't try more than 10 images at once or it'll take forever.

Because of the ES6 modules, if you want to run the script locally you'll need a server environment (npm/python HTTP server). The easiest way if you have python 3.x installed:

cd media-random-generator
python -m http.server 8000 --bind 127.0.0.1

Then open http://127.0.0.1:8000 in your browser.

Once you click on "reload," wait for a moment until you receive a functional URL; it will open a streamable stream in an iframe.
