After searching and trying lot of different and much more complex programs (I have even bought few of them), I have found this little peace of software, which has done everything what I need. I agree about "load pictures" button. I also have spend about 15 seconds to understand how to upload pictures. But it's really small issue. I would appreciate, if author may add iPhoto support to application - maybe some kind of integration.
Anyway, good small application and really nice price policy as well.
