Notas adicionais
- Files uploaded to the Wikimedia Commons will appear to be missing when accessed from other MediaWiki wikis.
- The timestamp from this module indicates the last time the image was modified.
- Since T360589, it is no longer guaranteed that the thumbnail URL returned by the API matches the requested thumbnail width (
iiurlwidth
). The thumbnail, which will be fetched from a pregenerated list, is either of the same width or larger. This is not issue when the browser can do the resizing, but if you do require the exact size, you now need to access the appropriate thumbnail URL directly.
