Photos in enlarged view in the viewer blurry

[neal]

Many photos when seen in the viewer in IA are blurry. Can this be fixed, or what is the cause?

This happens when IMatch Anywhere cannot access the original files (JPG) or there is no cache image and IMA cannot create a cache image. IMA then falls back to blowing up the thumbnail as a last resort.

Make sure the images are on the same server running IMA or run IMA under a user account that can access the original images if they are on a different computer. More details are in the IMA help for Admins.
