After reading through this topic, and this one, and this one, I’m not entirely sure what Discourse does with large images. My previous understanding is that there is no software resizing done, just CSS - that image size was limited by
maximum image upload size in kB and that was that. If a larger image is a remote file it gets linked, otherwise you just can’t upload it.
But now I’m confused because those topics mention downsizing and optimizing, which I didn’t think was happening because I’ve never seen it in practice that I’ve been aware of. I also have no idea what the
Maximum number of megapixels allowed for an image limit applies to. Does this prevent uploading images larger than that, or do images that exceed that limit get resized so long as they’re <
max upload size?
If it’s the latter, why is the default setting for megapixels so huge relative to the default max upload size? It seems extraordinarily unlikely that somebody will want to post a 51 megapixel image that is smaller than 4096 kB.
What I want is for users to conveniently upload whatever they have without worrying about file sizes and resolutions, and for the software to deliver something appropriate that doesn’t kill mobile users and people on slower connections. Is this currently possible just by adjusting
max image size and
