Media images not full width

Hi guys

My media images are suddenly leaving an offset on either side. The image is full size at over 1000 pixels.
It normally would fill up the width to the but now it leaves an offset on either side.

I would like to get the images back to their normal width.
Can someone please hep me.

Hi Bogdan

thanks for getting back to me.
My problem is probably a silly one. Here are two article links.
The first shows the images at full width holding the ends of and lining up with the text.

then without any settings change i suddenly have my images cropping in and not lining up with my text anymore. But also full size and large images.

I cant seem to get them back to full width.

What might have changed?

Thanks a lot Bogdan

It seems to have worked. I think it was the photon plugin on jetpack. I have deactivated it. Hopefully i still get the same performance without it. However, it seems my mobile display has gone all fuzzy now. I didnt do anything else, I just deleted all my cache and deactivated the photon. When i reactivate it, it still remains fuzzy… You can view my mobile version with the same link above and then minimizing to the portrait mobile orientation.
