Big chance that you have already made use of this site and its features. But nevertheless for some still interesting to have a look at it.
When you have some pictures at an event and want to share in movie format, this is the ultimate site to do so. Upload your pictures, choose a song or upload your own, and that’s it. Nothing more nothing less.
I assume that you are not going to use it for all your photos, but if you like to share some photos on e.g. Youtube it’s easy, fast and nice to watch.
Have fun, like I did.
