Right click and save to your computer.
You may use these images for your projects, both personal or commercial. Decorate your web site, get creative with a digital scrapbook or just have fun with them. If you use them on another web site you are not required to link back to this site (though it would be appreciated) but I do refuse the right to add them to any other online image database.
I have deliberately made these larger than you normally find in order to maintain image quality for those who need them large.
