WikiHealth:Image use policy

This policy explains how we use images (and, to some extent, other media) at WikiHealth.

Copyleft

All images on WikiHealth must comply with our copyleft. They should almost always be original work by the person uploading them; see copyright details for more info on exceptions to this.

Copyright information on images must be added to image pages. Images without copyright information are subject to deletion. If you don't have it, or know it, don't add the image to Wikitravel. When in doubt, leave it out.

Please give the following information: year of copyright, name of copyright owner, license(es). If the image is public domain (i.e. no copyright), state this instead.

The licenses must include the Creative Commons Attribution NonCommercial ShareAlike_2.5, but a picture can be released under additional licenses (e.g. GFDL,) if the image has been granted dual licensing. If you got the picture from a public source (web page, book, etc) then give a reference to the original source.

Image copyright templates can be used as a clear and easy way of indicating copywrite status of an image.

General use of images

Images are a great way to warm up an article, but be thoughtful about using them. No images are better than many irrelevant or inappropriate images. Allow your images to be concise; in other words, do not use 5 images when 1 will do.

Internal images

Images used in WikiHealth articles should be uploaded to the WikiHealth site. External images should not be used but they can be linked to.

Using Wikimedia images

Many images from the Wikimedia Commons or Wikipedia are as GFDL. While the WikiHealth licensing policy is under review, it is important to currently only use Wikipedia licenses that have a dual license, which is compatible with WikiHealth. Check the image data and the Wikipedian's uploader's User page for a possible dual-license note. .

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 is deprecated. It is technically inferior to PNG, which has about the same purpose. See http://burnallgifs.org/ for details.

Image sizes

Uploading high-quality source images is encouraged. Images should be less than 4Mb total size, and preferably less than 2Mb.

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 Adding 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 "cystic_acne.jpg", or "tibia_bone.jpg", or whatever. 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 us from having name clashes.
