I've had a look through Picasa and can find no options for this, and have drawn a blank online. Perhaps it's just one of those awkward 'You are simply expecting too much' questions?
As soon as I have transferred my digital photographs to my computer
I rename them so that the file name relates to the subject of the photograph
and to keep them in order i.e. 005 Tower of London.jpg.
When I display them full screen on my computer or on my TV the filename is not visible.
Is it possible to put the filename minus extension onto the picture as a caption?
It would be preferable to do this as a batch process rather than one at a time.
