Thanks for uploading Image:Acrux.png. I notice the 'image' page currently doesn't specify who created the content, so the copyright status is therefore unclear. If you have not created this media yourself then you need to argue that we have the right to use the media on Wikimedia Commons (see copyright tagging below). If you have not created the media yourself then you should also specify where you found it, i.e., in most cases link to the website where you got it, and the terms of use for content from that page.

If the media also doesn't have a copyright tag then you must also add one. If you created/took the picture, audio, or video then you can use {{GFDL-self}} to release it under the GFDL or {{PD-self}} to release it into the public domain. See Commons:Copyright tags for the full list of copyright tags that you can use.

Note that any unsourced and untagged images will be deleted one week after they have been uploaded, as described on criteria for speedy deletion. If you have uploaded other media, please check that you have specified their source and copyright tagged them, too. You can find all your uploads using the Gallery tool.

Hi, You included this artist impression of a Black Hole. Unfortunately it is not a good artists impression as they obviously didn't understand what consitutes a black hole. I hope to replace it. --81.132.246.132 23:10, 27 August 2007 (UTC)

I came here to say exactly the opposite. This picture is impressive, and fits with what I would expect (except that I would have expected some distortion with the stars). How was this image created? The proper way of doing this would be with a database with star information, and some heavy curved-space raytracing, and it looks like this might just be what has been done here. 193.157.233.147 20:27, 11 September 2007 (UTC)
It was indeed done by a ray tracing program in curved space. This should be explained some days in an article published in a peer reviewed journal, when I have time to write down all this. Btw, the star always appear as poinlike objets. The fact that they have an extended area on the screen results from saturation effects from your optical system, just as in usual astronomy pictures. Actually the hard part of the work lies in distorting the image, but not the stars (apart from the amplification and redshift/blueshift). Alain r 09:50, 15 October 2007 (UTC)

Tip: Categorizing imagesEdit

Hello, Alain r!

Tip: Add categories to your 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:

Uploadwizard-categories.png

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"). Pro-tip: The CommonSense tool can help you find the best category for your image.

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.

What are these images?Edit

Hi!

I was working on clearing up uncategorized images when I cam across the following files:

These files look to be to do with the CMBR and are obviously related, and could potentially be useful to explain some concept. Could you add a description as to what they are, so they could be used in an educational manner. If no description is added, it is quite possible they will be deleted as they can have no use without context. Cheers − Inductiveload (talk) 19:10, 3 February 2010 (UTC)
