Mail Merge into Word doc from Excel file not working?

Hi

I can't figure this one out. I have a jpeg image in the My Pictures folder. I have a mail merge source file (excel file) and a word document I'm trying to insert the picture into using mail merge. The example on the msdn website doesn't work as this is what I'm doing below.
I've tried to refresh the field by hitting F9 but still nothing. It just comes up with a blank picture frame in my word document.

In the excel file (source file) in the "Pictures" column I put the below.

"C:\\Documents and Settings\\Username\\My Documents\\My Pictures\\testpic.jpg"

In the word document field where I want to insert the picture I put the below.

{INCLUDEPICTURE { MERGEFIELD "Pictures" } \*MERGEFORMAT\D}

I've tried with and without the \D at the end but it makes no difference.
I have also tried with and without quotation marks around "Pictures". Still no difference.

Any clues as to how I can get this to work?

Thanks so much.
