Welcome to Wikimedia Commons, Alfa-ketosav!

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). You don't need technical skills in order to contribute here. Be bold when contributing and assume good faith when interacting with others. This is a wiki. 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). You can also contact an administrator on their talk page. If you have a specific copyright question, ask at the copyright village pump.

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.

Chemistry-image deletion-nominations

Thanks for finding poor-quality images that have better ones. If you nominate a file that is related to chemistry, please transclude the COM:DR discussion on Commons:WikiProject Chemistry/Deletion requests. Lots of chemists watch that page, and can help move those discussions along efficiently. DMacks (talk) 18:05, 27 August 2023 (UTC)

If you wish to have chemistry-related DRs being transcluded automatically in Commons:WikiProject Chemistry/Deletion requests, please see Commons talk:WikiProject Chemistry/Deletion requests for instructions. --Leyo 20:13, 17 November 2023 (UTC)

Karbamidciklus

Szia!

Láttam töröltetted az argináz által kataziált reakcióról szóló képet az általam készített karbamidciklus cikkből, mert JPEG formátumú és szerinted rossz minőségű... Oké, de ennyi erővel töröltetned kéne a többi reakciót és képletet is, amiket csináltam, mert ugyanúgy JPEG formátumúak és hasonló minőségűek... Szóval nem igazán értem miért kellett ezt. Hugrabug (talk) 19:15, 13 March 2024 (UTC)

Bocsánatot kérek, még nem volt rá időm. Megnéztem az általad feltöltött képeket, és voltak köztük PNG formátumúak. A JPG nem elfogadott képformátum a vonalvázakhoz vagy reakcióegyenletekhez, mivel veszteséges. Ajánlott az SVG, vannak jó programok, melyekkel SVG-fájlokat lehet készíteni, mint pl. az Inkscape.
