Your welcome. You need to click the Thumbnail image to see a larger image; the thumbnail will open up into either a larger popup image or into its own web page depending on your web browser settings.

The actual image sizes are 1:1 with the original menu sizes, ie: direct snapshots.
Once you have opened the full size image(s) you can right-click them & choose Save Image As ... to your computer where you can expand the dimensions manually via your computer's image viewer.
