Huh???

Who said anything about deleting the desktop. I'm talking about using DELTREE or RMDIR on the folder containing the file. The reason for not being able to delete it normally usually is a reeeally long filename, which Windows won't recognise. When deleting the folder in the commandprompt the filename will be ignored.

In case the file can't be deleted, try the same thing in safe mode.

If someone actually puts their desktop as the share folder, then he/she deserves to have it deleted.

I'm hoping you mean C:\Documents and Settings\**Your username**\Desktop\(Folder with image you want to remove)

If so then:

Go to Start-->Run type cmd in the window and press enter

It will look like this: C:\Documents and Settings\**Your username**

Now type cd desktop and press enter

Type rmdir (Folder with image you want to remove) and press enter

Then the image should be deleted in the folder you deleted

if an error or access denied message pops up, then start the PC in safe mode (hold down F8 when restarting and choose safe mode.) Then try the same thing.
