I need to update the Open Graph Image for linkedin when being shared. I changed it on Facebook and Plus but not on Linkedin. Is there any workaround on this?

We are in the process of creating more self-service tools for the developer community, but until those tools are completed, you will need to wait for the cache period to expire, which will

I'm new to Facebook Open Graph Protocol . I have been trying to figure out what the meaning of the HTML prefix attribute is.

First -- I do not believe this is a duplicate issue. I've searched for same or similar problems on SO extensively, and due to the nature of troubleshooting before asking, I believe this problem is unique. Facebook cannot grasp my og:image files and I have tried every usual solution. I'm beginning to think it might have something to do with https://... I have checked http://developers.facebook.com/tools/debug and have zero warnings or errors. It is finding the images we linked to in the " og:image ", but they're showing up blank. When we click the image(s), however, they DO exist and it takes
