I have my wallpaper set to SlideShow from my Pictures folder. Sometimes, I'd like to know which picture I'm looking at. Is there a gadget or other way to display the wallpaper file name in Windows 7?
Here's a script (with installation picture) that will allow you to check the name of the current image.
This script adds a Desktop Background File Location to the context menu in Windows 7 so that you can see what file is being shown in the slideshow. Here are the instructions for the script. Please check out this page for further details.
