If you expand it it up you will find the picture is of a massive steam engine in full flight, impressive machine and photograph.
Regards cancelling, definately, they messed up let them take the blame and if they don't and someone outbids them you are even beter off !
If you cancel it and then they change their mind afterwards they may complain to eBay about dubious practice/favouring other buyers, need to be on your guard.
I would never cancel a buyers bid except in exceptional circumstances, but I will readily block any that have messed me around so they don't do it again.

edit - Hi Ms M have fun
