This is the post in question

http://superuser.com/questions/117623/inserting-a-jpg-picture-into-a-cell-in-microsoft-excel-2007

If you click on the duplicate you get taken to http://superuser.com/questions/584650/how-do-i-load-external-images-into-excel

If you click on that, you are returned to the first link. 

This means, I think, that http://superuser.com/questions/117623/inserting-a-jpg-picture-into-a-cell-in-microsoft-excel-2007 should be re-opened; it's not a duplicate if it came first? 

The problem is, I'm trying to close http://superuser.com/questions/767203/excel-filling-images-using-a-reference-image as a duplicate to the above but I can't:

![enter image description here][1]

So, I guess this just means the system can't handle this and therefore the duplicate rules that site applies can't be applied in this case?

Is this a bug in the sense we can't close posts like this.
