What is a talking image
Talking image refers to an image with an audio payload appended at the end of image data. Currently OGG and MP3 audio formats are supported.
How do I add talking images to my webpage?
You use the regular
<img> tag but add an additional attribute called
data-audio, in which you set the options. Eg:
<img src="cool.gif" data-audio="autoplay loop">.
Options for the

- sync - try to sync the animation and the audio. There is no guarantee they will be in sync.
- loop - loop the audio

How can I create talking images?
The idea behind talking images is to append OGG or MP3 data to an existing image file - nothing more than that.
On Linux / Mac:
$ cat music.ogg >> funny.gif
$ cat beethoven.mp3 >> welcome.jpg
> copy /b funny.gif + music.ogg funny-music.gif
There are some 'clean' images and audio snippets in the
resources directory, play around with it.
Note: Audio file should be appended to the image file to create a valid talking file. Reversing the order will generate a corrupted file.
Why is it called Talking Image?
