and named Internet Explorer Wallpaper.bmp and a file search for "internet explorer wallpaper.bmp" (and YES, you do want to include the quotation marks so you don't get a really long list) will point you right to it. by default that location would be:
C:\Documents and Settings\{user_namr}\Application Data\Microsoft\Internet Explorer\internet explorer wallpaper.bmp

Do be aware that since it is loaded it will remain on the desktop even after deletion so be sure you make use of the desktop properties and select your old and preferred wallpaper (or whatever else you prefer). If your old wallpaper was selected the same way as the one you are getting rid of (right clicking an image in your browser and selecting to set as wallpaper) it will be gone because only one is saved by that name, new selections overwrite the old one.
