go $fsck yourself

I recently saw a self-hosted imgix/cloudinary alternative. I thought I starred it on gh, but apparently not and I can’t remember the name.

Edit
I think this was it:
https://github.com/imgproxy/imgproxy

But also, on a second read of your post, I now realize what you are looking for is right here:
https://squoosh.app/

It’s open source and it’s entirely client-side. It allows you to customize the settings to compress your image to the file size and format you need and maintain as much as the quality as possible. I can’t think of a simpler solution that works across all your devices.

To add to that, to effectively use docker and basically anything important for self-hosting is to learn the basics of Linux.

A good resource for that is https://learnlinux.tv/

If reposting memes, then why not do a quick reverse image search and grab a better version, as well? It seriously only takes mere seconds most of the time.

Tineye works great, but there’s also Google reverse image search when that doesn’t provide the results you hope for.

Not only does this generally improve the experience for everyone, but it also makes the platform much more appealing to outsiders that care about quality and will drive more quality users to Lemmy. On top of quality, but also things like links to and information about the creators, which is especially important for things like comics because the more people that know where to find the creators the more those creators can keep making their art.

Obviously, I do my best to contribute to this, but the more people that join in the better.
