Hi I made a Facebook feed plugin. Its a simple plugin that gets the Facebook posts from the Facebook graph and displays the result in custom html templates.

But some of the images are not showing when Photon is enabled. For example, the Facebook graph gives the url: https://scontent.xx.fbcdn.net/v/t1.0-1/p50x50/531073_287582807985582_653744962_n.jpg?oh=c4b9888f665ef8fc11ce2bce22016ab0&oe=580037E8

Then Photon changes the url into: https://i2.wp.com/scontent.xx.fbcdn.net/v/t1.0-1/p50x50/531073_287582807985582_653744962_n.jpg?w=800&ssl=1 which doesn’t work.

Its seems random, some image urls get changed, others are not. I tried disabling Photon in my plugin as described on this page: https://ethitter.com/2013/07/disable-jetpacks-photon-module-in-specific-situations/ but without success.

Is there any way to prevent Photon from messing up the image urls in my plugin?

Photon will indeed be applied to all image URLs. Only URLs including specific parameters will be excluded from Photon.

In your case, Photon returns a broken image because Facebook blocks direct access to the image:

curl -svv 'https://scontent.xx.fbcdn.net/v/t1.0-1/p50x50/531073_287582807985582_653744962_n.jpg'

To solve this issue, you could use the jetpack_photon_skip_image to exclude specific images from Photon, like for example image URLs using a specific Facebook domain:

That should help!
