Images are not handled efficiently
Problem: Images load very slowly (eg you can actually watch profile images load in line by line).
Assumed reason: When uploading an image, which happens for nearly everything in MoodleNet, there appears to be no actual resizing on the backend. Images are resized only on the front end with CSS. This approach causes slowness and increases bandwidth terribly, making MoodleNet less useful globally.
Solution: After upload, resize and store optimised images correctly on the backend
