Imageboard
An imageboard (IB) is a type of Internet forum that focuses on the posting of images, often alongside text and discussion. The first imageboards were created in Japan as an extension of the textboard concept. These sites later inspired the creation of a number of English-language imageboards.
Imageboards, similar to bulletin board systems, are used for discussions of a variety of topics. The primary focus of imageboards, however, is directed away from text posts, and is instead placed on picture posts. The two share many of the same structures, including separate forums for separate topics, as well as similar audiences. Imageboards are much more transitory with content—on some boards (especially highly trafficked ones), the thread deletion time can be as little as 10 minutes. The most popular English language imageboard, 4chan, similarly has a large variety of topics.
Imageboards are also different from online galleries in that most of the works posted are not made by the poster, but instead are taken from other online sources: galleries, other imageboards, and edited pictures.
Most imageboards and 2channel-style discussion boards allow (and encourage) anonymous posting and use a system of tripcodes instead of registration. A tripcode is the hashed (one-way encrypted) result of a password that allows one's identity to be recognized without storing data about users. Entering a particular password will let one "sign" one's posts with the tripcode generated from that password. Trying to take another user's tripcode and compute their password from it (for instance, to make posts that appear to come from a particular person) is somewhat computationally difficult. For those who want a custom tripcode, however, there are custom tripcode generators (which are technically tripcode crackers) available, such as Meriken's Tripcode Engine and MTY_CL. Anonymity is considered to be one of the advantages of an imageboard, and some boards have from time to time removed the ability to post with a name altogether (known as "forced anonymity").
Because tripcodes can be cracked given enough time, some imageboards, such as 4chan and 8chan, implement a "secure" tripcode. A secure tripcode is not reproducible across different imageboards; it works by prepending a secure salt to the tripcode which, barring security hacker intrusion, is known only to the server's staff. It therefore functions closer to a username than to a cryptographic signature; this is why QAnon could not verify themselves on another website when 8chan went down in late 2019.
A booru is a type of imageboard designed primarily for hosting and categorizing large collections of images, typically fan art, anime, manga, or other niche media. The term booru comes from the Japanese word "board" (ボード, bōdo), re-pronounced in a way that mimics how early anime/manga fans would romanize it online. It’s also a nod to Danbooru (Japanese for cardboard), the original and most well-known booru site.
Boorus were created as a companion to image boards to archive and index posted media, as opposed to the policy of imageboards of deleting them when a post becomes too old. Booru also help international users to find media hosted by non-English gallery host, or hosts which often lack English tags, in particular Pixiv.
The source code for Danbooru is publicly available on GitHub. The most popular forks of Danbooru include Gelbooru and e621.net, which maintain their own custom feature sets, and allowed post types. Some fandoms use their own booru software, such as Derpibooru, the largest and most popular imageboard for My Little Pony fan art.
