Film Loop Studio is a free download and creates a a slideshow of any images or photos. It offers collages, title frames, text, tattoos, bubbles, frames and transparency tools to enhance story telling for both Mac and PC users.
I found it very easy to produce a slideshow of photographs, however there's no audio capability so far. The slideshow can then be added to a website, a blog, etc. The advertisements appearing on the side of the player are distracting but I suppose they have to generate some income after all.
World Press Network uses Film Loop for some of its photo essays. Here's a feature on India's Snake Charmers on the dying craft of snake charming in Orissa. The photographs are by Adrian Fisk.
