Sharepoint discussion missing avitar photo but present in mysite

Question

My mysites is employee.sharepoint
The discussion is it.sharepoint.

The mysites had the user photos populated.  In a discussion board on it.sharepoint, I am missing the avatar/user photo next to the user's name.

It receive The query string "ID" is missing or invalid.
And it tries to take me to http://it.sharepoint/Infrastructure/_layouts/userdisp.aspx?ID=

The ULS viewer sees the entry as

Microsoft.SharePoint.SPException: The query string "ID" is missing or invalid.  
at Microsoft.SharePoint.ApplicationPages.UserDisplayEditPageBase.OnInit(EventArgs e)   
at Microsoft.SharePoint.ApplicationPages.UserDisplayPage.OnInit(EventArgs evtargs)   
at System.Web.UI.Control.InitRecursive(Control namingContainer)   
at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

How do I get the photos to show up in the discussions?

Answer 1

the query string is the "?ID=" part. THe error is the fact that there should be a UserID value after "=". As a test try to create a discussion board on the same web app as your mysite and see if the picture shows up. that might at least tell you if the issue is related to communication across web applications.
