hello and thanks for this great plugin.

In the last few weeks I am having the following problem: when I share k2 items on facebook, the corresponding image is not passed onto facebook or if so, it is blurry.

Please find attached an image showing the current situation and how it was working in the past.

Any idea on what could be the problem? Thank you
