If you're a regular around here, you know that I share a free background image each week. If you're new - here it is - a new, free, background image each week - for you to download and use in Powerpoint (or another similar presentation program) or in any of your projects at home, work, school, or church. Use them however and wherever you like. I only ask that you share them freely and that you tell others that you found them here.
For those who like to know the details and such - this week's picture is of a section of tree growth rings.
