I created an image, copy-pasted the link somewhere and now it says it's not found. Why?

You should NOT directly link images from our servers.

All the user actions generates an awful lot of image files (several hundreds of gigabytes every day), and most of them are never used or accessed again, so they are automatically deleted after a while.

Ezgif is an image manipulation tool, not a hosting site, and we don't have the resources to host all of this. Sorry!

You should save the image when you have finished working with it the computer, and upload it to a hosting site like https://imgur.com/ if you wish to share it online, to be safe it stays available for a long period of time.
