Files that are only likely to be referenced from a single page can be added at the same time as you enter the page or news item. You do this by using the File Attachment option and selecting the local file for uploading. However, please note that all these images will be loaded into the /file directory, so if the local file name is already in use then Drupal will automatically load the file using a slightly different name. You can reference the image using
<a img src="/files/xxx.extension ...
(see more in section 5) or a document using
<a href="/files/xxx.extension>document name or title</a>
Files that are likely to be used more widely, or that should be part of a more organised folder structure, e.g. the British Go Journal, can be uploaded by FTP. Contact the webmaster for help and advice on this.
In general files should be uploaded in a neutral format and proprietary formats should be avoided. It's also desirable that formats that prevent the inclusion of viruses should also be avoided - this means that we don't recommend the use of Microsoft Office formats (no matter what software produces them).
The system holds a list of valid file extensions and the maximum file size for upload; these can be changed if need be (the last changeable for each user).
But, in any event if this sounds too prescriptive, remember that our mantra is Content is King, so upload the content even if you break these rules.
