If you use the @@images view (note the final 's'), you do not need the image filename, the field identifier is enough (for a News Item, the image field is named image).
So change the img src attribute in your .pt like this:
src string:${programme/url}/@@images/image
It will be the full original image, but you can also specify the size like this:
src string:${programme/url}/@@images/image/thumb
