Enable responsive image sizes on mobile[edit]
- Originated from GW2W:BUG#srcset attribute missing for images on mobile devices.
- Title
- Enable responsive image sizes on mobile
- Type
- Amendment of LocalSettings.php
- Reason
- There is a phabricator ticket which details how the srcset tags are stripped out by mw:Extension:MobileFrontEnd for mobile viewers. On high resolution devices, this has the effect of rendering images as slightly blurry (degrades the user experience). Paraphrasing the phabricator wall of text; srcset attributes historically resulted in images being downloaded twice from the server - this was fixed in browsers years ago - however the mediawiki mobile code still removes the tags which exist on desktops as a kind of "optimisation" which is no longer required. Setting
$wgMFStripResponsiveImages
overrides this default behaviour and leaves the srcset attribute in place.
- Instructions
- Not applicable. This change has already been committed to the test version of this wiki (MW 1.38.2), and as such detailed instructions are not specified here (summarised; add
$wgMFStripResponsiveImages = false;
to LocalSettings.php.
- Possible pitfalls
- None identified.
