If you click on an image, which is uploaded and linked in your wiki – you will be redirected to the meta page of this file. Here you can discover a lot e.g.
- size of the image
- meta information of the image
- you can see on which pages the image is used
- and it is also possible to upload a new version of this file
Especially this last point is very important not only for images but also for files. Because if you have a new version of this file, which might be linked or used in several other pages, just click on „upload a new version“. Afterwards upload an „updated“ modification. Now, in every page this file is used, the new version will be shown – you don’t have to edit and update every page.
So you avoid spamming your wiki with too many files that might be named like „photo-account-manager“ „photo-account-manager-new“…. Just replace the original file with this functionality and you have replaced the file. Like you know it from the version history of articles, also the files have their own version history with the time a version has been uploaded and the user who did that. In the same way as you do it for articles, you can also rollback to a former version.
