Articles in Wikitravel can be greatly enhanced with the strategic addition of illustrative images. This article describes how to add images to a page. It assumes that you know:
Images should only be uploaded to Wikitravel Shared. The software will automatically check both the Shared and the local image repositories. If the same filename exists on both the local site and the Shared site, the local image has precedence.
Please use thumbnails unless you have a good reason not to. The standard recipe for a thumbnail is as follows:
This will produce a right-aligned thumbnail with a description below; the image will expand to full size if clicked on. For example, the thumbnail on the right uses Image:Saddleback Pier.JPG from Shared, and it's created like this:
Please use thumbnails unless you have a good reason not to. To change the size of the image, see "Sizing" below.
Some other formatting possibilities are:
Providing a description of the image is useful for low-resolution computers, where the image may not be rendered, and for accessibility for disabled Wikitravel users.
Frame and Caption
You can also give a frame and a caption text to an image by
Framing a picture in this manner will default the picture to its original size.
Normally, images should be specified as thumbnails and should not have a size set - this way they will default to the size set in the registered user's preferences.
If you do have an exceptionally good reason to override the defaults set by the user or not to use thumbnails, then to set the
You must add the letters "px" after the image size. Recommended maximum sizes are:
You do not need to specify the height of the image, as the size will automatically scale to match the width you have entered.
If you want to specify an exact image size (width) which is not the same as the original, selecting a factor of the original may result in a clearer scaled image. For example, if the original is 800 pixels wide, 400 (1:2), 267 (1:3) or 200 (1:4) will scale nicely; for 640, try 320 (1:2) or 160 (1:4). This is particularly important for images containing small text, such as maps.
You can also set thumbnail image sizes to be a factor of the default selected by the registered user. Specify the size component as "upright=factor". (This only works if "thumb" is also specified - see the English Wikipedia documentation for details.) Just specifying "upright", without the factor argument, uses a default value of 0.75, which is a sensible default for images in portrait (as opposed to landscape orientation).
There are a bunch of great sources on the web for images compatible with our CC-by-SA copyleft. Good starting places include Wikimedia Commons and Flickr  — just make sure that the images you find are indeed listed under a compatible license.
Other useful sources include geograph  (for UK images), ...
Google image search is a useful tool for finding images with a compatible licence. Go to Google advanced image search  and in the filter options select labelled for commercial reuse with modification. This should ensure that almost all of the images returned in your search will be compatible with our CC-by-SA copyleft.
Google's Picasa web-service  also has a good collection of CC licensed images, which for unknown reasons rarely show up in regular image searches. Do a search, and then select Show options on top of the search results, and click Commercial Use under the licensing header in the sidebar which appears on the left.
