Using Basic Theme but want to use custom picture

[rasrjs]

We want to use the Basic Theme option. However we would like to have a custom picture for the background. Is this possible and how would we do this?
Currently we are using the My Themes option?
Thank you

Do you mean desktop wallpaper? I've been doing this for years with 98 and XP. Open your filing system, and scroll down to C:\Windows>Web>Wallpaper You can drop any pictures you want into that folder. Make them the right size for your monitor first, otherwise they'll be stretched or too small for the screen. I make a black border around mine for my desktop icons so that they don't obscure my picture.
