Does that really scale though? The load on a server is not dependent on the number of users, but on the number of communities from other server that the sum of user is subscribing to.

Which means if you have a server for 100 users, you still need to pay for the 1000s giant communities that those users are subscribing to, as they are being copied over in your server.

So if you have a few mega server like Lemmy.world, they each pay say 10000£ in hosting a month (number taken out of my hat), which is fine because they have as many users that can contribute to it financially ( via donations, ads etc.). But small servers won’t be able to support that load and will ultimately close.

That sounds like a design flaw if you ask me but i did not see anyone mentioning it so maybe i’m misunderstanding.

is there a !woosh for the replies to your comment?

I got a 403 the first time I visited it, then when I went to the source, and back to the image it works. I suspect they have a cookie or something to detect that you’re a valid user.

Because this is a different domain the cookie would not come with the image request.

Just a wild guess

Actually I found a way to make it work, bit hacky, but you can add #.jpg at the end of your URL. For example, here is your osaka picture as an image post pointing directly to twitter

https://lemmy.world/post/341872

I’ve used

https://pbs.twimg.com/media/Foojf9RaEAA1GM-?format=png&name=small#.jpg

As the URL to force image detection

(if you’re not a dev, I assume this is your face right now, sorry about this:

I’m not a lemmy dev, I just took a look at their repository

I believe it’s the regex that detects if something is an image

A reddit image URL is :

https://i.redd.it/2obhjz2wb37b1.jpg
or
https://preview.redd.it/7s1p7mal707b1.jpg?width=640&crop=smart&auto=webp&v=enabled&s=f741210c6c54fed7c3ed06aaabdb1f0a49fd46cb

in both cases it has “.jpg” (with the dot) in it so it passes the regex. It does not need to finish with it.

Whereas the image your provided does not have that in it.

You can instead download the image and post it like this, or similarly take a screenshot.

I believe that sort of website does this on purpose to make sure they don’t waste server resources on other website that do not drive any ad revenue to them.

Holy Cow that’s a good guide, thanks for this.

Thanks, I’ll have a look over all that over the weekend.
