I was trying to figure out how to add sparkle to my jeweled bow center photos (diamond mesh, rhinestones, etc.) and Google directed me to this website: http://glitterboo.com/
I was in heaven...it's exactly what I need and it even has animation for enhancing Christmas trees, water and the like.
You can choose to use it for free or you can pay $8.95 for ONE YEAR to get access to all the other features. The best part is they do not automatically bill you for subsequent years! After ten minutes on the site, I paid for the upgrade.
Love it! Check it out for yourself!
