First steps tutorial Our first steps tour and our frequently asked questions 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 (Wikimedia Commons only accepts free content).

Getting help More information is available at the community portal. You may ask questions at the help desk, village pump or on IRC channel #wikimedia-commons (webchat).

Goodies, tips, and tricks Put Babel boxes on your user page so others know what languages you can speak and indicate your graphic abilities. You can find the files you have uploaded in your Uploads. Please sign your name on Talk pages by typing ~~~~. To link to an image page without embedding the image, type: [[:File:Foo.jpg]], which produces: File:Foo.jpg. You may enable gadgets (custom features) for your account. There are several tools to upload files. Have you edited Wikipedia before? This guide might be useful. Made a mistake? Do you want to have a file renamed or moved? Use the move link and wait for an authorized user to rename it. Do you want to have your recently uploaded picture removed? Tag it as {{speedy|reason here}}. For more information read the deletion guidelines.

Thanks for uploading high-quality chemistry diagrams! When you add categories, please only the add the most-specific ones relevant to the image, not all the more-general ones as well. That is, only use the subcategory, not the parent category. For example, File:Azulene_synthesis_2.png you marked it:

1. Category:Chemistry
2. Category:Organic reactions
3. Category:Organic chemistry
4. Category:Organic compounds

But categories are a hierarchy rather than a flat pool of tags. Cats 2–4 are all subcats of cat 1, so cat 1 should not also be listed. Both cat 2 and cat 4 are subcats of cat 3, so cat 3 should not also be listed. But there are also specific subcats for many different reactions. And the main value of this image is the synthesis of the product, so listing the specicic cat for it is useful. I'm not sure if there is a specific category for the original substrate, but it at least can be classified.

1. Category:Chemistry
2. Category:Organic reactions → Category:Diels-Alder reaction
3. Category:Organic chemistry
4. Category:Organic compounds → Category:Furanones Category:Azulene

Thanks for pointing out! I will have my future wikimedia uploads to contain the correct categories, and try my best to relabel the ones that I have already uploaded. Pygos (talk) 09:45, 16 May 2024 (UTC)
