Hi,
Currently, the title of images uploaded to story is formed from the file name. Names are usually a random set of letters and numbers, something like: f7131f0b07b4b55eacb3c588b28d3c39_large.jpg
As a result the image title is f7131f0b07b4b55eacb3c588b28d3c39_large
The ability to add title images in the story upload form will be very useful for both users and SEO.
