Thomas pic from five's milkshake

Five's milkshake Thomas website includes an image of a CGI Thomas in the background but you can't save it.

However, I found out a way to download the image, I checked the page source, got the link and there we have it:

The image was located half way down the contents of the page source which contained a link to the image highlighted in dark blue and underlined.

The image features Thomas in the countryside which is used on milkshake's Thomas website and icons.
