Why old image links break

You clicked a picture in an old forum thread, a newspaper page or a blog comment, and instead of the image you landed here. The link looks like it should still work: a short address, a file name, a familiar extension. Nothing about it says the picture is gone, and often it is not gone at all. What has broken is the address, not the photograph.

What those short image addresses were

For a long stretch of the web's history the normal way to put a picture into a discussion was to upload it to a free image host. You picked a file, the host stored it, and it handed you back a short link with a random string in it. That string was only a key in the host's own database: it carried no folder, no description, no hint of what the picture showed. You pasted the link into a post, the forum turned it into a thumbnail, and the discussion moved on.

The picture then lived in one place only. The post that showed it held nothing but a pointer. If the pointer ever stopped resolving, the post lost its illustration, even though the words around it survived untouched.

Why the pointer stops resolving

Free hosting is cheap to start and expensive to keep. Hosts close, get sold, or quietly drop the part of the service that costs them the most, which is storage and bandwidth. When ownership changes, the new owner rarely inherits the files, and more rarely still keeps the script that turned a random key back into a picture.

There are smaller reasons too. Some hosts deleted uploads that nobody had viewed for a long time. Some began refusing requests that arrived from other sites, so the same link worked in a browser tab and failed inside a post. Some changed the shape of their addresses and broke every link already pasted elsewhere. In each case the file may still exist somewhere; the route to it does not.

How to find the picture now

Start with the page that linked it. Forums often keep a thumbnail of their own, and quoted replies frequently repeat the caption or the file name, which is enough to search with. If the picture was discussed at all, the discussion usually describes it.

Next, try the file name in a search engine and in a reverse image search. Pictures that travelled around forums were re-uploaded many times, and one of those copies is often still online. Public collections that keep old pages sometimes stored the image alongside the page that used it. Finally, ask the person who posted it: people who cared enough to share a picture frequently still have the original on a disk somewhere.

How to post pictures so the link lasts

Upload where the conversation lives, so that the picture and the words stay in the same place. Keep your own copy of the original file, because a link is not a backup. Prefer a service that gives you an account and a way to export everything you have uploaded. Write a short caption next to the image describing what is in it, since text can still be searched long after a link has died. If the picture matters, attach it rather than pointing at it.

Short image links that once pointed at this domain no longer resolve to a file. What is here instead is an explanation of how this part of the internet behaves when it stops working, which is the question you were asking when you clicked.
