If your image is
not the maximum size for the gallery page your thumbnail may
be distorted. This exaggeration is most noticeable in vertical
If you want to avoid the distortion please
make a box in Photoshop that is 447 pixels wide and 350 pixels
Next drop your image into the box, or
format your image so it fits into the box.
Then save this newly
as the file for the registry. This will help ease any distortion
that may occur.
