I've been using the excellent Flickr Gallery plugin for a while but while upgrading a site to WP3.5 and the Twenty Twelve theme, I stumbled across oEmbeds and notice that Flickr is supported natively.
I did a quick test and sure enough, simply placing the URL to a Flickr image page produces an image in the post – but it's a tiny 320 pixels wide. Given the content space appears to be about 625 pixels wide, it would be much better to have the 500 pixel image returned.
I've found mention of the max width setting, which it now appears is not present in the WP3.5 admin interface. The only reason I was considering switching to the native capability was to remove customisation (the plugin I have is dead easy to use). Do I have to create a child theme simply to set this width? Or am I missing something?
Any tips appreciated.
