PostcardViewer Options
1. Columns – This is the number of thumbnail menus columns on the album web page. For example a value of 4 with an album of 12 photos yields a 4 column by 3 row thumbnail grid.
2. Frame Width – This is the width of the photo frame in pixels. Usually a value of 5 to 15 works well here.
3. Cell Dimension – The size of the area around each image. Make it slightly larger than Max. Image Size
4. Max. Image Size – This should be the same as the values (in pixels) used in your Aperture export preset.
5. Zoom in and Zoom out Percentage – Relative size of the photo in zoomed in and out mode. Typically, this can be left at the 100% and 25% default values unless you want to do something special.
