Accessing main picture of wikipedia page by API

You can get the thumbnail of any wikipedia page using prop=pageimages. For example:

http://en.wikipedia.org/w/api.php?action=query&titles=Al-Farabi&prop=pageimages&format=json&pithumbsize=100

And you will get the thumbnail full URL.

http://en.wikipedia.org/w/api.php

Look at prop=images.

It returns an array of image filenames that are used in the parsed page. You then have the option of making another API call to find out the full image URL, e.g.: action=query&titles=Image:INSERT_EXAMPLE_FILE_NAME_HERE.jpg&prop=imageinfo&iiprop=url

or to calculate the URL via the filename's hash.

Unfortunately, while the array of images returned by prop=images is in the order they are found on the page, the first can not be guaranteed to be the image in the info box because sometimes a page will include an image before the infobox (most of the time icons for metadata about the page: e.g. "this article is locked").

Searching the array of images for the first image that includes the page title is probably the best guess for the infobox image.

This is good way to get the Main Image of a page in wikipedia

Check out the MediaWiki API example for getting the main picture of a wikipedia page: https://www.mediawiki.org/wiki/API:Page_info_in_search_results.

As other's have mentioned, you would use prop=pageimages in your API query.

If you also want the image description, you would use prop=pageimages|pageterms instead in your API query.

You can get the original image using piprop=original. Or you can get a thumbnail image with a specified width/height. For a thumbnail with width/height=600, piprop=thumbnail&pithumbsize=600. If you omit either, the image returned in the API callback will default to a thumbnail with width/height of 50px.

If you are requesting results in JSON format, you should always use formatversion=2 in your API query (i.e., format=json&formatversion=2) because it makes retrieving the image from the query easier.
