imgbb.com is what I use quite often cause imgur is trash.

I run my own file host: kimiga.aishitei.ru. Files get uploaded from clipboard using ShareX. This allows me to have control over my own files, how long they last or if they should last forever, and I'm not dependent on a benevolent developer preventing my links from rotting 8 years from now when they close down their host due to it costing them too much or simply because they got bored of being a sysadmin/dealing with issues (or users) of their site.

I used to donate to pomf.se and used that as the image host because I was a supporter of the sysadmin - but it eventually grew too large and had to shut down. Then a bunch of pomf.se clones popped up and I used one of those - can't remember which one but then that one shut down too after only a year. That's when I decided to set up my own host.

I don't allow other users on the site because I don't feel like having to deal with what users upload, DMCA requests, morally gray areas, etc.

.ru domains are sometimes blocked so my backup is catbox.moe

I host my own images on my server using nginx to serve them from /var/www/images. You can see an example here: https://images.nunosempere.com/blog/2023/02/19/bayesian-adjustment-to-rethink-priorities-welfare-range-estimates/ignore-the-prior.png

The nginx configuration I'm using is

server {

        root /var/www/images;

        index index.html index.htm index.nginx-debian.html;

        server_name images.nunosempere.com;

        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ =404;
        }

    listen [::]:443 ssl ipv6only=on; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/images.nunosempere.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/images.nunosempere.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}
server {
    if ($host = images.nunosempere.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

        listen 80;
        listen [::]:80;

        server_name images.nunosempere.com;
    return 404; # managed by Certbot

}

I have for long used postimages.org whenever I needed one. But imgbb.com is also an equally good option.

catbox.moe

So lemmy.world lets you just copypaste images directly from your snipping tool and hosts them on lemmy.world/pictrs

Kbin sadly does not do this, no idea if other lemmy instances do this

discord (if you have discord btw) or 0x0

Discord. You can get the links for images and videos posted in it, and they work outside their original site.

Wait, I'm simply pasting them into my comment. Why should I use a dedicated image holster?
