How To's & Info
For a great education concerning graphics, and how they all work together in scrapbooking, etc., you can visit ScrapGirls.Com. They have a forum with WONDERFUL, knowledgeable people and all sorts of tutorials on how to use different software programs to create things with graphics.
As far as purchasing the graphics from my site, just place the items in your cart, click on the "secure checkout" link at the top of any page when you're ready to checkout and follow the steps to check out. After payment is processed, you'll be directed back to a page where you can then download your graphics (assuming that you pay by PayPal or credit card...if by check or money order, your links won't be activated until after payment clears).
At that point, you can click on the download links, choose "save file," and make note of where your downloader is placing the files on your computer. Once downloaded, you'll have zip files that will need to be unzipped before you can use the graphics. If you don't have a zip program, you can get a free one here: http://peazip.sourceforge.net/. After the files have been unzipped, you will be able to open them from within most any type of program.
