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 contributing here and assume good faith for the intentions of others. This is a wiki — it is really easy.
There seems to be a problem regarding the description and/or licensing of this particular file. It has been found that you've added in the image's description only a Template that's not a license and although it provides useful information about the image, it's not a valid license. Could you please resolve this problem, adding the license in the image linked above? You can edit the description page and change the text. Uploading a new version of the file does not change the description of the file. This page may give you more hints on which license to choose. Thank you.
Some contents have been listed at Commons:Deletion requests so that the community can discuss whether they should be kept or not. We would appreciate it if you could go to voice your opinion about this at their entry.
If you created these pages, please note that the fact that they have been proposed for deletion does not necessarily mean that we do not value your kind contribution. It simply means that one person believes that there is some specific problem with them, such as a copyright issue.
Please remember to respond to and – if appropriate – contradict the arguments supporting deletion. Arguments which focus on the nominator will not affect the result of the nomination. Thank you!
Thank you for your contributions. Your image or other content, Open Source World Conference, was recently deleted, or will soon be deleted, in accordance with our process and policies, because it was not, or is not, within our scope. Please review our project scope, but in short, Commons is targeted at educational media files including photographs, diagrams, animations, music, spoken text and video clips. The expression “educational” is to be understood according to its broad meaning of “providing knowledge; instructional or informative”. Wikimedia Commons does not contain text articles like encyclopedia articles, textbooks, news, word definitions and such. Each of these other kinds of content have their own projects: Wikipedia, Wikibooks, Wikisource, Wikinews, Wiktionary and Wikiquote. If the content seems to fit the scope of one of those other projects, please consider contributing it there. Otherwise, consider an alternative outlet. If you think that the deletion was in error because the contribution really was in scope, you can appeal it at Commons:Undeletion requests, giving a reason why it fits our scope to help others evaluate the matter. Thank you for your understanding.
Please see this page for more information on how to confirm permission, and Commons:Permission if you would like to understand why we ask for permission when uploading work that is not your own.
The file probably has been deleted. If you sent a permission, try to send it again after 14 days. Do not re-upload. When the OTRS-member processes your mail, the file can be undeleted. Additionally you can request undeletion here, providing a link to the File-page on Commons where it was uploaded ([[:File:JosepJover8.jpg]]) and the above demanded information in your request.
