You can improve Wikimedia Commons most if you contribute what you can do best:

Contribute your work

If you're a good photographer, don't hesitate to contribute your valuable images. If you're a good designer, look which diagrams and animations are badly needed. If you're a good musician or film/theater artist, do not hesitate to publish your own records of your performances of free pieces here.

Contribute your skills

However you do not need to upload your own files. There is plenty of other very important work to do:

• Translate help texts into a language other than English.
• Improve images.
• Identify unknown objects.
• Contribute your legal knowledge on copyright questions and deletion requests.

Contribute your time

You even do not need to be an artist or good at writing help texts. If you feel at home with creating order from chaos, then we could use your helping hand!

• Anytime you see a file with incomplete licensing or source information, tag it {{subst:nsd}}.
• Give uncategorized pages a category.
• Move files into relevant subcategories
• Free media resources are waiting for an inclusion into this project.
• Nominate or vote for Featured Pictures (registration required).

In order to be able to upload files on Wikimedia Commons, you need to be logged in. You can register at the "Log in / create account" link in the upper right corner and enter a user name that will be used at all of your uploads/edits on images and texts. However if you just want to edit pages you don't need to be logged in (although it is encouraged). If you have taken advantage of unified login, then you are already signed up at Commons.

Our first steps help file and our FAQ will help you a lot after registration. They explain how to customize the interface (for example the language), how to upload files and our basic licensing policy. You don't need technical skills in order to contribute here. Be bold contributing here and assume good faith for the intentions of others. This is a wiki - it is really easy.

More information is available at the Community Portal. You may ask questions at the Village Pump or on IRC channel #wikimedia-commons.

Files on Wikimedia Commons are organized in categories and galleries. An overview of the categories we use is available on the Main Page.

If you want to upload large numbers of images, the program Commonist will be helpful. If you need specific information on tools for viewing or editing our content please see the software page.

We hope that you will enjoy it here and that you will have fun.
