Images should be in one of the following formats:
  
It might be possible to find the copyright holder in the image file's comment. Read [[Wikitravel:Comments in image files|comments in image files]] for details.
+
*'''JPEG''' - for photographs

If you got the picture from a public source (web page, book, etc) then give a reference to the original.

Diagrams and maps should also have a vector-format source file. We prefer SVG, but other vector formats (Adobe Illustrator, PostScript) are better than nothing.

Revision as of 09:57, 22 July 2006

This policy explains how we use images (and, to some extent, other media) on Wikitravel Shared and the Wikitravel sites.

Contents

Copyleft license

All images on Wikitravel Shared and the Wikitravel sites must comply with the copyleft license. See also the copyright details for more information.

Note:images from Wikipedia are often licensed under the GFDL only and therefor not compatible with Wikitravel, unless they are double-licensed with our copyleft license.

Image formats

Images should be in one of the following formats:

  • JPEG - for photographs
  • PNG - for text, maps, or computer-generated images
  • SVG - for source of maps or other diagrams

The GIF format should not be used, since it is technically inferior to PNG, which has about the same purpose.

Diagrams and maps should also have a vector-format source file. We prefer SVG, but other vector formats (Adobe Illustrator, PostScript) are better than nothing.

Avoid people in photos

In general, photos of people will be removed from Wikitravel Shared. There are two reasons for this policy:

  1. A photo of the Taj Mahal is useful for travellers; a photo of a travel companion in a funny hat standing in front of the Taj Mahal is not. In general, we don't really want pictures of travellers or other people in Wikitravel. Some exceptions might be for particular sports or activities or crowd scenes or illustrating some costume or uniform.
  2. In the United States and elsewhere human beings have privacy rights, that is, a right to control the use of their own image, even if they didn't create the image. Image creators need to get authorization from human subjects of photos to publish the images. See http://www.danheller.com/model-release.html for a description of why and when a model release is required. A general rule of thumb is that if an image contains a subject that is identifiable, a model release is needed.

Image information

The image information, i e the text entered in the "summary" field, must be in english.

Summary

The "Summary" field should contain the following information:

  • Image description
  • Where the image/photo was taken
  • Who took/created the image
  • When the image was taken/created
  • Copyright information on images must be added to image pages. Images without copyright information are subject to deletion. Wikitravel Shared have special templates for this - use them.

The licenses must include the Creative Commons Attribution-ShareAlike License Version 1.0, but a picture can be released under additional licenses (e.g. GFDL, see Wikitravel:dual licensing for details).

Minimal use of images

Travellers may be using Wikitravel from networks with very low bandwidth. In some countries, an Internet café with 10 computers connected to a single 56k modem is fairly common. Image use in articles should be kept at the minimum necessary.

This doesn't mean that 0 images is preferred to 1 image, but that no more images than are necessary to get across a point or impression should be used.

Internal images

Images used in Wikitravel articles should be uploaded to Wikitravel Shared. External images should not be used. Also, avoid linking to external image pages since the reader mat find it annoying to jump from site to site in search of images only.

Using Wikimedia images

Many images from the Wikimedia Commons or Wikipedia are licensed as GFDL and thus not compatible with Wikitravel. However, an increasing number of Wikimedia contributors are choosing to dual-license their work under Attribution-ShareAlike 1.0, which is compatible, so check the image data and the uploader's user page for a possible dual-license note. Check this link to find pages with dual license on Wikimedia Commons. At the moment you cannot link images directly from commons, instead you have to upload the files to Wikitravel Shared, too.

Image sizes

Images should be less than 512kB total size, and preferably less than 256kB. There is a hard limit of 8Mb on uploads.

Pixel dimensions should be 1536x2048 (3 megapixels) or smaller, as this is enough for a 6"x4.5" print at 300 DPI (half a guidebook page). When displayed, pictures can be automatically scaled to smaller thumbnails; see How to add an image for details.

Image file names

Image file names should be somewhat meaningful. Many digital cameras give images names like "IMG00001.JPG". You should try to rename these files to something like "cathedral_in_cologne.jpg", or "spanish_steps.jpg", etc. Use descriptive names with full words and underscores ("_") between the words.

This makes it easier for other people to include the image in articles, and it keeps Wikitravel Shared from having name clashes.

Do not include the image size in the file name.

People in photos

In general, photos of people will be removed from Wikitravel. There are two reasons for this policy:

  1. A photo of the Taj Mahal is useful for travellers; a photo of your girlfriend in a funny hat standing in front of the Taj Mahal is not. In general, we don't really want pictures of travellers or other people in Wikitravel. Some exceptions might be for particular sports or activities or crowd scenes or illustrating some costume or uniform.
  2. In the United States and elsewhere human beings have privacy rights, that is, a right to control the use of their own image, even if they didn't create the image. Image creators need to get authorization from human subjects of photos to publish the images. See http://www.danheller.com/model-release.html for a description of why and when a model release is required. A general rule of thumb is that if an image contains a subject that is identifiable, a model release is needed.

Other media

One of Wikitravel's goals is to have Wikitravel articles useful as printed pages. Use of other media files — like digital sound clips or video images — is therefore deprecated.
