displaying the image number in the thumbnail view

[mala]

When in the image view, the number of the image is displayed as x/Y, Y being the total number of images
in the album and x being the number of the displayed image inside the album.

I would like to have these numbers displayed also in the thumbnail view, under the thumbnails, either over, or under the title of the image, or next to
it, or even instead of. This makes referencing to the image simpler (the file names in our gallery sikinos.unige.ch/NOB are rather long and cumbersome).
Otherwise one has to go to the image view or count the thumbnails.
