Everyone has a ton of photographs on their phone. I never get around to sharing them. Sharalike makes it super simple to create slideshows with music (Straight out of Compton sounds perfect when playing in the background of my preschooler at the beach). Full disclosure: I'm an advisor to Sharalike because I like what they're doing...
These guys convert pictures into raw HTML5 slideshows which look like videos in Facebook but are actually slideshows which take 1/10th of the time to make, they're one of the 6 FB dev partners (among vimeo, soundcloud) who are allowed to play native HTML5 embeds in FB timelines: https://www.facebook.com/etienne...
