Well, there is also ngx_pagespeed, but assuming the conversion happens as a separate step, it's also easy to configure nginx [1] to serve the appropriate asset based on advertised Accept header.

https://bugzilla.wikimedia.org/show_bug.cgi?id=25611 --- Comment #12 from Mathias Schindler --- Since the initial opening of this bug Google has significantly added to the webp software and added support for more metadata, transparency and a lossless coding. webp as of today would fit for shrinking both lossy jpeg and lossless png thumbnails in Wikipedia articles for those browsers supporting it.

https://bugzilla.wikimedia.org/show_bug.cgi?id=25611 --- Comment #10 from cesar --- this could be done by using Google mod_pagespeed since it does on the fly WebP conversion. https://developers.google.com/speed/docs/mod_pagespeed/filter-image-optimize ModPagespeedEnableFilters convert_jpeg_to_webp Enabling convert_jpeg_to_webp causes the image optimizer to create webp images whenever it would otherwise create jpegs. The webp images are only served to modern browsers that support the format.

Current Status:
Google Chrome (stable) and the current stable Opera Web Browser now support
WebP encoded image files.
In en.wikipedia.org, a test script exists that replaces jpeg thumbnails with a
(toolserver generated) WebP image.
Add:
importScript('User:Magnus Manske/webp.js');
into your user specific .js file (such as User:[Name]/vector.js)

I might have come up with another early approach that will prevent this scenario. 1. A customized user skin .js/.css file to alter any thumbnail linkn(every link to a .jpg that starts with http://upload.wikimedia.org/wikipedia/commons/thumb/) to another url, possibly toolserver.org or webptest.whateverdomain.tld) to ask the browser to get the image from this site. 2. The js could containt a browser switch. Browser not supporting webp would not get the altered url. If someone installs the user-mod and changes browsers, there would not be the undesirable result you described. -- Configure bugmail: https://bugzilla.wikimedia.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug.

The main reason to implement it at all is to reduce bandwidth usage; as a per-user option it's a geek curiosity, while as a default that can act on all requests it would actually be able to have wide effect. > > One downside as a user pref: do *all* your browsers support webp? > > Right now, there is no browser supporting WebP.

Well, here's the scenario I was thinking of: a) user enables WebP thumbnails while logged in via Chrome-next b) later, user logs into site from another computer running a different browser, and can't see any thumbnails on the site. That browser might be a netbook, tablet, e-reader, smartphone, game console, or a computer that doesn't have any WebP-capable browser. On the other hand if what the user option is for is to enable an Accept-header check which determines which format gets used, then that's probably not a problem -- that next login would use JPEG thumbnails. -- Configure bugmail: https://bugzilla.wikimedia.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug.
