Edited ... to change emphasis of my question ...
Martin had shown the images using the original URL for the pics in the ebay listing [now removed].
Normally, linking to the ebay listing is preffered for such actions as this avoids problems of copyright breach of using seller's images and possible knock-on effects on the GMB.
But does the copyright problem apply when the image link is made with the original URL? Is this what is now quiite often discussed as "theft of bandwidth"?
