Tip: Categorizing images
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:
[[Category:Astronomical diagrams]]
[[Category:Comets]]
This will make the diagram show up in the categories "Astronomical diagrams" and "Comets".
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.BotMultichillT 06:14, 28 January 2009 (UTC)

In all cases, please do not take the dispute personally. It is never intended as such. Thank you! --Matt (talk) 20:02, 6 February 2009 (UTC) |
The Image:LeuckartWallach1.png is now converted zo Image:LeuckartWallach1.svg. I hope this is what you mean. If not, let me know. Regards --Roland1952 (talk) 00:18, 7 February 2009 (UTC)
- Yes, thanks for the quick fix. Matt (talk) 10:41, 7 February 2009 (UTC)
Ich nehme an, es ist OK die inkorrekte PNG-Version zu löschen, nachdem ja nun eine korrekte SVG-Grafik existiert, oder? Mit dem Löschen von PNGs ist man auf Commons im Allgemeinen eben restriktiver als in der de-WP. --Leyo 11:20, 20 March 2009 (UTC)
- Sicher und Danke, habe nicht immer ans Löschen lassen gedacht. Gruß --Roland1952 (talk) 13:19, 21 March 2009 (UTC)
Hi there
I think you have made an error in this image: you have portrayed 4-aminopyridine, instead of 4-dimethylaminopyridine. Perhaps you can fix it? Thank you. --Rifleman 82 (talk) 11:54, 22 March 2009 (UTC)
- Many thanks for your attention, changes are made. --Roland1952 (talk) 13:46, 22 March 2009 (UTC)
Hallo Roland, mir ist aufgefallen, dass du eine neue Version der Strukturformel hochgeladen hast. Ich habe die alte Version wiederhergestellt, weil die Datei mit Absicht auf diese Art und Weise und entsprechend den Richtlinien der Redaktion Chemie gezeichnet ist. Viele meiner Strukturformeln werden auch in anderen Projekten genutzt, z.B. bei wikibooks und sind in der Regel genau aufeinander abgestimmt (in diesem Fall vgl. die Box im Artikel de:Ribose und entsprechende Boxen der anderen Zuckerartikel). Daher fände ich es besser, wenn du deine Formel unter einem anderen Dateinamen hochlädst. Besten Gruß, --NEUROtiker ⇌ 18:03, 28 March 2009 (UTC)
- Hallo NEUROtiker, ist geschehen. Auch ich zeichne meine Strukturformeln nach WEIS, allerdings sind hier für perspektivische Zeichnungen keine Maßgaben aufgeführt, so dass z.B. Bindungen im Vordergrund nicht eindeutig spezifiziert sind, ebenso keine Winkel. Auch kommen Unterschiede dadurch zustande, dass unterschiedliche Auflösungen vorhanden sind. Gruß --Roland1952 (talk) 00:01, 29 March 2009 (UTC)
- Zur Erklärung: Schuld war meine Anfrage und ein einheitliches Layout bei wikiversity. --Leyo 21:42, 29 March 2009 (UTC)
- Hallo Leyo, was heißt hier Schuld? Ich verstehe jetzt den Einwand. Auf der französischen Seite bin ich fertig. Hoffe ist soweit ok, hat noch keiner gemeckert (bisher ;-))). Gruß --Roland1952 (talk) 22:32, 29 March 2009 (UTC)
- Naja, vielleicht wäre Auslöser treffender gewesen. Vielen Dank für deine Arbeit. Der Artikel ist nun optisch viel ansprechender und die unschönen JPG-Strukturformeln können demnächst entsorgt werden. --Leyo 08:17, 30 March 2009 (UTC)

There is an error on the first molecule of the reaction scheme. It should start from an aromatic amine.—Apcpca (talk) 12:05, 8 June 2009 (UTC)
- Hello Apcpca, many thanks for your attention. I changed the scheme and hope it will be correct now. --Roland1952 (talk) 19:38, 8 June 2009 (UTC)
- All correct now, except that it should be NaX and not NaOH on the first arrow. Thanks.—Apcpca (talk) 22:26, 8 June 2009 (UTC)
- I hope, this will be finally correct now, if not, please let me know. --Roland1952 (talk) 22:48, 8 June 2009 (UTC)
- Now I understand it. I think is better now (at least clearer for me). Sorry to cause you so much trouble. Many thanks.—Apcpca (talk) 23:41, 8 June 2009 (UTC)
- I hope, this will be finally correct now, if not, please let me know. --Roland1952 (talk) 22:48, 8 June 2009 (UTC)
- No problem.--Roland1952 (talk) 07:10, 9 June 2009 (UTC)

Monobook
Hallo Roland, du hattest Roland1952/monobook.js erstellt. Ich habe sie dir in deinen Benutzernamensraum verschoben, wo sie nun auch funktionieren sollte. Gruesse, →Nagy 16:21, 1 July 2009 (UTC)
- Hallo Nagy, danke für die Mühe. Wusste nicht, dass es USER: sein muss, war mein erster Versuch. Gruß --Roland1952 (talk) 17:16, 1 July 2009 (UTC)

Hallo Roland,
wenn ich mich nicht irre, müsste die Anzahl der Hs bei der Alkylkette links 35 betragen (CnH2n+1). Gruß, --NEUROtiker ⇌ 18:01, 26 September 2009 (UTC)
- Hallo Neurotiker, hast natürlich recht. Ist geändert. Hatte es einfach aus der *png-Datei übernommen, ohne nachzudenken (Asche über mein Haupt). Gruß -- Roland1952 (talk) 12:14, 29 September 2009 (UTC)
Hallo Roland. Die Struktur ist gemäss Orci nicht sinnvoll. Falls ich die Grafik löschen soll, bitte mit {{Speedy}} taggen. --Leyo 08:40, 10 November 2009 (UTC)
- Hallo Leyo, Vorlage ist eingefügt, hatte ich glaube ich auch nur als Vorschlag gezeichmet: kein Problem. Gruß -- Roland1952 (talk) 09:02, 10 November 2009 (UTC)
Hallo, im Reaktionsmechanismus scheint der Tippfehler ( anstatt ) immer noch vorhanden zu sein. Im Text darunter ist der Mechanismus richtig erklärt.
Gruß, Dreifragreng
- Manchmal gibt es Tage....... Hoffe jetzt
OK. Wenn nicht suche ich den nächsten Waffenschrank. Viele Grüße -- Roland1952 (talk) 21:41, 6 January 2010 (UTC)
Servus Roland, dein Tetraaminkupfer-Kation ist leider ein Tetramethylkupfer-Kation. --MarkusZi (talk) 17:22, 22 January 2010 (UTC)
- Danke, siehe meine Disk.-Seite. Gruß -- Roland1952 (talk) 18:26, 22 January 2010 (UTC)
Hallo Roland, ich glaube, bei der Datei zur Konjugation sind Dir zwei Fehler unterlaufen: zumnächst sind die beiden Verbindungen A und B sowieso identisch, d. h. sie sollten von vornherein identische Kationen bilden, zum zweiten ist in den Verbindungen nicht Chlor als Substituent vorhanden, sondern eine Methylgruppe, somit würde der der Abgang von Cl- auch keinen Sinn machen, obwohl im Text auf der Seite zur Konjugation in der Chemie dies so erklärt ist. Ich hoffe, ich liege hier nicht ganz falsch, ansonsten bitte ich Dich, den Fehler zu korrigieren.
Gruß -- Jagaloisl (talk) 10:21, 26 February 2010 (UTC)
- Hallo Jagaloisl, zunächst Danke für deinen Hinweis. Natürlich hast du recht, dass da irgendwas nicht stimmt. Hatte seinerzeit auch das Bild geändert, aber, aus welchen Gründen auch immer, nicht hochgeladen. Hoffe, dass das Bild jetzt in Ordnung ist, sonst melde dich bitte wieder. Gruß -- Roland1952 (talk) 11:43, 26 February 2010 (UTC)
Hallo! Könntest du dieses Bild bitte nochmal korrigieren (H2O statt HO2)? --ahellwig (talk) 12:02, 1 May 2010 (UTC)
- Hallo Ahellwig, das Bild war ok, habe den Servercache geleert. Das Bild müsste jetzt auch bei dir richtig angezeigt werden. Gruß --Roland1952 (talk) 13:55, 1 May 2010 (UTC)
Oripavin
Hi there,
A user raised a technical question about an image you made; they're not quite sure if it is an error or not, therefore (in live help) I advised them to post the question on the English Wikipedia Reference Desk. So, please see [[Wikipedia:Reference desk/Science#Oripavin structure: wrong?]].
Cheers! Chzz ► 20:54, 23 September 2010 (UTC)
Hallo. Die Darstellung der Reaktion in der Grafik stimmt zwar, allerdings sollte vielleicht die Schreibweise der einzelnen Strukturen angeglichen werden. Mal werden die gleichen Methylgruppen mit H3C, mal mit CH3 bezeichnet. Mal lässt man das CH2, an dem das Nucleophil angreift, weg (der Chemie-bewanderte erkennt es natürlich im Knick der Linie zwischen dem Nu und dem C-), mal schreibt man es hin. Gruß. --153.96.151.103 16:16, 14 January 2011 (UTC)
Lizenz und Datumsformat
Hallo Roland. Könntest du in Zukunft für Strukturformeln den Lizenzbaustein {{PD-chem}} und für das Datumsformat JJJJ-MM-TT
, also für heute 2011-06-02
verwenden? Zum Einsparen von Tipparbeit könnte Commons:Hochladen/Chemie nützlich sein. --Leyo 21:29, 2 June 2011 (UTC)
Frasch process
Hi there
I noticed File:Frasch_Bohrkopf.svg, which I was hoping to use in the English article Frasch process. Do you still have the original files? Would it be possible for you to prepare an English version of this image? Thanks! --Rifleman 82 (talk) 22:13, 16 June 2011 (UTC)
