Automatically resize large images

[efskap]

Noticed that some people try to fry images from their phone camera (why..?), which (being like 5000x5000 px) take AGES to fry.

Not a good look.

Ok but, what if some people want to preserve the original resolution?

I'm gonna list all alternatives I can think of:

• Warn: The website shows a warning if the image exceeds a size threshold, and suggests the user to resize it themselves using some image-editor
• Cap (absolute): The size gets clamped to a hardcoded value, preferably 480p (720p is overrated)
• Fraction (relative): The image gets scaled proportional to its size, preferably 50% (I guess?)

All 3 alternatives have 2 possible sub-alternatives (total: 6), because the website may show a checkbox to disable the feature. Cap & Fraction could offer an "ultra-low quality mode", that either caps the size at 144p or 12.5%, respectively
