Im glad I got it.
I like so many others, was discouraged and ticked off when I downloaded a picture I really liked; only to find it extremely large once I attempted to set it as a desktop.
I deleted many photos because I wasnt going to be using them.
Then I came across this app. it certainly does help!
My only complaint is that when you are using the app and click on the preview icon, the preview they show of your picture is not correct. Once I save it and then use it, the picture is bigger than the preview but still smaller than originally. I think even though this is an easy app, you still have to play around with it a little. I do recommend it, because you are now able to shrink your pictures and use them!
