To rename a group of picture in the same folder, fisrt select them all (Edit | Select all or CTRL+A).
Then click on File | Rename. This will put the first picture in name edit mode. Insert a meanful name (ex: Summer 2005 holiday.jpg) and XP will automatically rename all the pictures with the new file name, adding incremental numbers (ex: Summer 2005 holiday (1).jpg; Summer 2005 holiday (2).jpg; Summer 2005 holiday (3).jpg; etc.)
I am running windows xp professional. I know there is a simple way you can name a group of pictures the same. How?
