Thanks a lot for contributing to the Wikimedia Commons! Here's a tip to make your uploads more useful: Why not add some categories to describe them? This will help more people to find and use them.
Here's how:
1) If you're using the UploadWizard, you can add categories to each file when you describe it. Just click "more options" for the file and add the categories which make sense:
2) You can also pick the file from your list of uploads, edit the file description page, and manually add the category code at the end of the page.
[[Category:Category name]]
For example, if you are uploading a diagram showing the orbits of comets, you add the following code:
When picking categories, try to choose a specific category ("Astronomical diagrams") over a generic one ("Illustrations").
Thanks again for your uploads! More information about categorization can be found in Commons:Categories, and don't hesitate to leave a note on the help desk.
