Help: Upload Whitelist
When uploading a post, instead of uploading a file you may supply a direct image URL. In order for this to work, the image must be hosted on a domain that is whitelisted by e621.
When submitting a new entry, a percent symbol may be used as a wildcard. Wildcards should only be used to match subdomains (such as
%.example.com). It is unsafe to match part of a domain itself! For example, the pattern %example.com allows an attacker to create a domain like
badexample.com to gain access to our IP address.
The only field visible to the public is the note, so make sure any public entries have a useful note! Any entries with a blank note or marked as hidden will not be visible to the public.
Admins and up are not susceptible to the whitelist, and as such are able to upload from any domain.
