I was not able to find a DSM-210 section in the forum so trying the next best area.
My problem is similar to others in this section.  I purchased a DSM-210 picture frame looking forward to having it read pictures wirelessly from my Iomega NAS.  The basic set-up works with the DSM seeing the nas, folders, and pictures.  However, when the pictures are presented on the frame, the are very fuzzy.  The pictures look like a thumbnail level of resolution was pulled from the server and then expanded on the frame.  When the frame pulls pictures from my Windows 7 PC everything looks fine.  
I checked with the Iomega folks and they think it is a problem with the frame.  My guess is that the d-link folks will say it is a problem with the Iomega NAS.  Anyone else have this problem?  I not able to find a setting anywhere that selects the resolution of the picture pulled from the NAS.
