Creating thumbnails and screen captures
It is useful to use existing images as a template for size and shape when creating thumbnails and screen captures for display in the Gallery. As an example, you can use the images that are in:
\Library\Functionality\Change Language Wizard.gallery_Files
Image dimensions
When creating new thumbnails or screen captures, use these image dimensions:
Thumbnails: 75 x 100 pixels
Screen captures: 330 x 380 pixels
