Slide.ly is a free web application that grabs all your photos/albums from multiple popular social networks, such as Facebook, Flickr, Instagram, Picasa and Google Images, letting you create gorgeous slideshows with a mix of your favorite music tracks and effects.
The app is easy-to-use and comes with a slick interface. Once you’ve connected all your accounts, the service will let you pick and arrange images from different sources. For instance, you can select five photos from Facebook, two from Instagram, a few from the local disk and so on. When the images have been added, you will be able to arrange or shuffle them, add your favorite music from YouTube or SoundCloud, and add bright dots, spots, dust or glow effects to your slideshow.
When you’ve created the perfect slideshow, you can share it with your buddies on Facebook or other social networks, copy its link, email or embed it on your website or blog. Clicking the embed button allows users to select a player size and copy the code for it from a pop-up.
