You can create sliding photo albums (called Story albums)to appear on your blog like this one I made to go on my class blog.
This album is powered by
- Add to my blog
Uploading is easy, you simply select the photos you want from your computer and upload them one by one, then you choose how you want your album to look and the site will generate a code for you to copy and paste into your blog.
You can also record and add your voice but I haven't experimented with that yet :)
