WordCamp: Jetpack doesn't use Photon for Gallery images and images using HTTPS

[jeherve]

By design, Jetpack only uses Photon for images inserted via HTTP. All HTTPS images will be ignored by Photon.

Since some (all?) of the WordCamp sites now use HTTPS as their site URL, galleries are now built using HTTPS image paths. As a result, the gallery images are resized by the browser, instead of using Photon.

-- See ​https://lyon.wordcamp.org/2015/les-photos/

To force Jetpack to use Photon anyway, we'd need to use the following filter:

add_filter( 'jetpack_photon_reject_https', '__return_false' );

I'm not sure where you would typically add such a tweak. I don't see any functionality plugin, so in one of the mu-plugins maybe?

In 1663:

Jetpack Tweaks: Consolidate our Jetpack tweaks into a single mu-plugin.

See #1073

Yeah, all WordCamp sites are using HTTPS now, on the front-end and back-end.

I consolidated all of our Jetpack tweaks into mu-plugins/jetpack-tweaks.php, so that'd be the best place for this.

Force-activate Photon for images served via HTTPS

I added a patch. I couldn't test it though, as I'm not sure how to get the whole meta site running locally.

In 1665:

Jetpack Tweaks: Enable Photon support for HTTPS URLs.

Fixes #1073

Thanks Jeremy, it worked great :)

For future reference, you can setup ​the Meta Environment to get a copy of WordCamp.org (and other wporg sites) running locally.

Awesome, thanks for the link!
