downloading photos from wordpress

Two years ago my wife wrote a blog using wordpress about our travels. A publisher is now interested but wont make an offer until they have good quality copies of our pictures. We were horrified to realise that one of the sd cards is broken so we can not retrieve the photos….we did not back these ones up. My last hope is that the photos stored in images in wordpress were taken from the original SD and appear to be stored in their original sizes. We are desperate to get these back but there is no option to do this. I hear there may be a way by exporting from com to org but I dont know if this is true.

Please pleas help.

Thank you
