All images lost resolution when enable Photon

I should had mentioned it before. I’ using Jarida theme. If there is a compatibility issue.

check your featured image size in post.
it is
https://i2.wp.com/www.papadopoulosgiannis.gr/jarida/wp-content/uploads/2013/05/4c_n300.jpg?fit=300%2C160

171px*160px

but it should be
https://themes.tielabs.com/jarida/wp-content/uploads/2012/07/7413497016_9434c1917a_b-300×160.jpg

300px*160px

Even if I resize it at the proper size as you say it doesn’t change. Look at the post that the photo exists, I changed it but the slider and the news-box still have it at low resolution. And the widget at the right “News in pictures”, even this.
When I deactivate “Photon” All Pictures return to correct resolution.

put featured image in that size may help you

try this

Once photon has cached an image it will never recache it. So if you ‘fix’ an issue with your image, it won’t help, photon will just keep serving the old ‘broken’ image from before.

Hi,

funsail is correct. You need to change the file name for Photon to recache the image.
