I've already deleted them.
I've had to remove them all. You suffered one of the sites occasional quirks, it creates duplicated images but if you remove one it corrupts the others so you have to remove them all.
As for your links, if your images are in the Archives, First click on
Gallery, then you have to click on the Archives link in the centre of the title bar. Then your "My Photos" will shows the Archives images.
By default the system assumes images are in the main galleries.
