> * To place a logo anywhere in a web by typing **%MYLOGO%**
, simply define the variable on the web's [[WebPreferences]] page. You also have to upload `logo.gif` - this can be done by [[TWIKIWEBFileAttachment]] to `LogoTopic` (any topic name you choose):
> * **Set MYLOGO = %PUBURL%/%MAINWEB%/LogoTopic/logo.gif**
For more useful variables see the %TWIKIWEB%.TWikiVariables page.
