Editing a file
Files cannot be edited on GCpedia. To edit a file it will need to be downloaded. Use a suitable software program to perform the modifications. Once the changes are completed upload the file to GCpedia. The same filename may be used. This will overwrite the existing file.
If other versions (especially a larger version of an image) of the same file exists, link to them.
Files can be in the same category as other pages, but are treated separately: on the category page they are not included in the count of articles in the category, and they are displayed in a separate section, with for each a thumbnail and the name, see category page.
For categorizing a new file, the file page does not even have to be edited: the category tag can simply be put in the upload summary.
