A logo on a wiki is a symbol, image, or other design; graphical or textual, created by a wiki's owner to visually identify the wiki. In WikiIndex's articles of wikis, logos of said wikis shoud ideally be uploaded, appropriately categorized, and then wikilinked within its article infobox. Alternatively, wiki-logos may be hotlinked directly to their external wiki. The advantage of hotlinking is that if the logo is updated on the external wiki, then it will be not be necessary to re-upload the new updated logo here on WikiIndex. However, a disadvantage is that if the wiki's website has problems with connectivity, or goes offline and becomes inaccessible, its wiki-logo will no longer display here on WikiIndex. A further disadvantage is that hotlinking logos directly to their external website places a greater load on the WikiIndex server, to 'fetch' the logo from its host website, and then 'forward' the logo onto the users own browser. This 'fetch and forward' action takes place every time that its wiki's article-page is loaded (whereas local logos which are uploaded to WikiIndex are forwarded only once, then stored locally in the cache of the user's computer, unless a forced 'refresh' or purge of the page is manually requested by the user).
Implementation
MediaWiki
On wikis which are powered by MediaWiki, when using the popular MediaWiki skins such as Vector and MonoBook, the wiki-logo is placed in the top-left corner of every page on the wiki. Clicking-upon this logo takes oneself to its main page. The wiki-logo is a helpful reminder of what wiki oneself is using, since many wikis which use the same wiki-engine (especially with the same skin) look very similar, even identical, and one coud otherwise easily search or edit the wrong wiki by accident. These logos are usually around 135x135 pixels, although it is useful to create a larger logo in case oneself wishes to also use it as the logo for say, a Facebook page, or other social media or website for the wiki. See also Manual:$wgLogo.
Other wiki engines
Other wiki-engines (when using standard skins for that specific wiki-engine) will have the same visual 'similarity' between different wikis, as detailed above, for MediaWiki. However, logo placement on the page, and default logo sizes will vary from MediaWiki, but be unique to their own specific wiki-engine.
