This app is currently on sale on the Mac App Store for $2.99, so I gave it a try based on the positive reviews I read below.
In fact, this app is very easy to use, which is a good thing.
But at the same time I find it rather simplistic. The "frames" that this app comes with are actually only simple masks which will give your image a jagged border (or an oval, barrel shaped etc one, you get the idea). While I acknowlegde that this can look nice for mugs, T shirts and little pictures for your homepage sometimes, the use is limited, and this is not what I call "framing an image" anyway.
Yes, you can download real frame images from various places on the internet (i.e. freeware stuff from various collections) and use them together with EasyFrame. But I think one should not have to, they ought to be included. Hunting them down and installing them is tedious, and these frame images come in varying qualities and with different usage restrictions. And you can only ever use one frame at the same time, without any means to change its size or appearance.
So all in all I am disappointed. I understand that for some people this app is all they want or need, so I refrain from giving it a low star rating. But if you are like me and don't mind paying more for a more complete solution, you may want to check out ImageFramer. This is what I settled for — this app is still easy to use, but much more powerful and comes with a huge gallery of great looking frame borders that can be combined and customized at will. And it does render shadows!
But well, for a mug or T shirt, I'd perhaps still go with EasyFrame and one of its bundled simple masks, so I admit it does have its uses.
