The patch to add a new hook, 'ThumbnailBeforeProduceHTML', to
ThumbnailImage::toHtml method, in order to permit the user to manipulate the
image attributes before the HTML is rendered
We ran into this when trying to ensure that the images get updated promptly
when the user uploads a new file. Browsers tend to overcache, and MediaWiki
seems to currently offer no facilities to address this, though there are come
future plans to add file versioning.
Our (Knowledge Management group at Vistaprint inc.) proposed solution is to add
a new hook, 'ThumbnailBeforeProduceHTML', to ThumbnailImage::toHtml method.
This would allow the user to edit the src attribute and append a timestamp
parameter to it when the file's mtime changes.
We have implemented and tested this solution internally, and it works as
intended. The patchfile is attached.
